When that happens the racket will become shorter and wider and the side supports are all out of adjustment because the side supports are slinding down/up the outside of the racket as the standards move in because the side supports are connected to the standards. When adjusting the top and bottom supports they should just be touching but the tightening of the standard against the turntable should be tight enough they never slide.
EDIT: I would call Alpha and work out the problem if I couldn't fix it myself.

When you're dead you don't know you're dead. It's the same way when you're stupid.
