Thanks for the quick reply, let me detail an example below:
Step 2: Unpack: (as you see 52KG is already wrongly copied)
STEP 3: Repack on the same HU
So if I would now do this again without saving my OBD the weight stays the same.
However, if I would save my delivery and try this again we would have 76 total weight and 64 KG loading weight.
So it seems to occur each time we go into a delivery and perform the first repack action.
Thanks for input.
