I don't know why, but when the backpack has no NBT, it doesn't want to be sorted

I can't understand what the problem is. From what I see in the video may be sorting doesn't work in the second case? Can you be more specific

What are "Backpack without NBT" and "Backpack with NBT"

with nbt : with items in the backpack
without nbt : without items in the backpack

So I tested it and for some reason mouse clicks for that item are not processed the same way as for other items.

Since its just this item and a special version of it I would report this to Travellers Backpack authors.

ok
