Affects versions 1.21.x and higher
I used an NBT editor (specifically “IBE Editor” to stack unstackable items in a 1.20.4 world (because IBE Editor’s latest version was and still is 1.20.4). I then transfered the world to 1.21.4 (latest version at the time) and opened it to find stacked unstackable items had completely changed. Here is a list of what I was able to observe:
Doesn’t show item count
Shift clicking said stacked item will now fill up the inventory as if it had dropped 64 singles of the item instead of a full stack
Dropping a full stack and picking it back up also does the same thing as this ^^^
You can move a full stack of a unstackable item if its in a container of some sort and you press an inventory slot hotkey while hovering over said item.
You can also hover over said item and press the offhand key which still puts a full stack in your offhand as normal.
Items with less stack capacity (e.g. books, signs, ender pearls that only stack to 16) show the item count but only as 16 and then the behaviour is once again the same as the other items.
See this issues which also talks about the item count not showing when stacking unstackable items past 1:
I’m very confident the world transfer between versions and the IBE Editor mod itself are the problems. IBE Editor has been the most reliable NBT editor for me, and I’ve done world transfer many times in the past, stuff like this doesnt happen so I’m confident this is just a 1.21.x issue. unfortunately I don’t have any screenshots or footage of this because my laptop currently cannot record but you can try this out for yourself.
Environment
I thnk (maybe?) this bug is throughout all 1.21 versions
Bug found in 1.21.4
Singleplayer world
Used "IBE Editor" NBT editor mod in 1.20.4 to stack the unstackable items
Transferred the world with the stacked items from 1.20.4 to 1.21.4 when I found this bug in 1.21.4

loke at the video
Is your problem solved?
After some more testings, I can confirm that even on a 1.21.5 SERVER, the stacked items continue to behave weirdly as listed previously. Also, referring to AKAN5’s video, he offhands the stacked item first then puts in back in his inventory. There are some issues with this as this only works if you unoffhand it in a main inventory slot. If you open your inventory and then unoffhand it any slot, it will put a single from the stack in the slot you unoffhanded it and would remove 1 from the stack which would still end up staying in your inventory. With that saying, I humbly request that this bug report is put off of the Resolved status, as the problem is still not yet solved, because the normal behaviors are bugged. I’ll list them again just incase:
