Slipsheet Placement moved when case size changes. [PickMaster 5]

I am working on an old PM5 project that has been installed for about 1.5years. The customer has had to change the case sizes by a few mm in each dimension. I made the change today, and now the slipsheet is being placed offset and is hanging off of the pallet.

I cannot find anything that has changed about the slipsheets that would cause this.

Any thoughts?
