Qidi x-cf pro level issues

New purchase of a x cf pro. Went about the fast level auto off, everything went as is should, went to the fast level auto on and the build plate didnt stop going in the z axis hitting the extruder and bending the BL. Homed it out, attempted to re-level, same thing happened. Pulled the level plug from the extruder and tried the normal level auto off and the build plate would not stop in the z axis. the build plate bounces off the z limiters just fine, not sure what could be causing this, and have asked a few people on a fb group and theyre all lost as to what could be causing this. thanks.
