One Knob is loose, compared to the other 15..???

Hi, Im using the Midi Fighter Twister, just bought it to use for EQ control with LOGIC X… Its great,.. BUT, the controller up in the far right is a little looser than the other 15, its a bit weird when you jump to it, it doesn’t have as much resistance as teh other 15…Is this normal ??? Its a shame as the rest of teh build quality is really good… Or can it be adjusted.?? thanks
ALSO are there any over lay templates PDFs out there, so that I can print them…?
Thanks ROB

Can I take it that everybody else has a full working unit.? Thanks

Send it back for replacement.
