If you're saying those levelers are raising the playing surface by 2" then you haven't screwed them all the way in first.
I used these levelers: https://www.amazon.com/Swivel-Adjus...=1573666242&sprefix=leg+level,aps,142&sr=8-41
They have a minimum height of 1.3" and a maximum height of 2.6". I also have a 1/2" thick board underneath to disperse the load evenly over the floor.
