Bad Cushion

Define funky, and a better reply may be achieved. 😉
It's likely the rubber has come loose from the sub rail, if so you'd need to remove the rail, pull the cloth and put some glue on it.
Depending on how old they are, and how picky those using it are, you might want to just get a replacement set of rails and do a full recovery.
 
We've got a Valley local that likes to bounce balls up in the air after they hit the rail. I'm thinking the nose of the cushion is low. I'm not sure what the fix is but it just started doing it lately.

I wonder if this is something like the OP is seeing?
 
Low nose height will cause bouncing. Inch and 7/16 is where they should be. Simplest fix is remove the trim, loosen the bolts and lift the rail to the proper height and then tighten it back up to 7-8 Ft-lbs.

rails were just done a year ago with all new ridgeback, when i say funky i mean there is an extra bounce the ball like jumps off the rail extra bounce

yes it bounces like that off this table, even bpunces like that if you hit it up and back and up again
 
Ridgebacks definitely shouldn't be doing this. They are well designed and built (at least all the ones I've seen). It's likely the cabinets or how the cloth was installed. Did you see how the rail cloth was wrapped? I've noticed some people like to wrap the cloth over the top of the rail, and then cut it off at the bottom, causing the nose to dip slightly.
Are all the rails doing this, or just a few?

Here is a pic of the cloth having being removed at the bottom corner. Terrible idea.

not sure i wasn't there during installation but it was fine the first couple years

Why would a rail replacement do anything for playability? What happened to a rail that needs to be replaced?

Same way a new tire makes your car drive better if your old tires are bad.
New rails can also change the pocket angles and width making it easier or harder to pocket balls.

It's possible the rails were set at the proper height without shims, and nobody ever re-torqued the rail bolts (often overlooked). If the bolts become loose enough, the rails can shift.

Not a mech here...but do one and next week one on the other side goes. I would roll (no pun) with Sheldon. Replace all at once and you are good for years. You will not regret it.

there is a video of 2 rebounds off the rail one the initial hit than rolling back for a second hit
 
The usual cause of balls hopping is a low cushion nose. There are other causes, but this is the first suspect.

Get an adjustable square that measures to 1/32".

Measure the cushion nose height. Make sure it is between 1 3/8 and 1 7/16. Ideally, it should be between those two measurements... 1 13/32.

Ball can still hop when the nose height is measured at 1 7/16" if the body of the cushions are not in the proper position. The 63 1/2% of the ball, +/- 1% only applies to ONE thickness of sub rails, and ONE model of cushions, that's a 1 11/16" thick sub rail and K55 profile cushions, you can throw out the suggested rule of thumb for the 63 1/2% of the ball for all other makes of rails because that DON'T apply in their case!

Thanks for posting again

You are correct. That's why I posted "There are other causes, but this is the first suspect."

Not on a bar table. The way the rail cloth is installed is the first thing to check, because the rails are Ridgeback, therefore they were built correct, therefore the nose height would have been correct in the first place. So something else must be wrong. ALL Ridgeback rail blocks are made using the same molder, using the same cushions, and have a reputation for playing great, so nose height can't be the subject, there MUST be something else wrong.
