Not sure whats going on with this cabinet but I can't make any changes to it since I upgraded to 6.1.3. I could make all the changes I wanted in 6.1.2.
Went in to delete a shelf and a partition. Clicked on Main and started getting errors.
Were you working in the batch or room and sending cabinets to the cabinet editor in 6.1.2? There was a bug in 6.1.2 where if you took a cabinet from the batch/room to cabinet editor then return to batch/room and selected no to save changes, it would lose pe cuts for that cabinet If you did this, you would need to recreate your batch/room in 6.1.3 from your seed cabinets.
