Pumpkins won't stack

I'm going to add on to this one, rather than making a new one because I suspect it's the same issue.  I use an Ipad Air 1.

I've been having an issue where some items randomly won't stack.  It normally happens for me when I've been breaking blocks and then I try to combine them with a partial stack in a chest.  I think I first noticed it when I was raiding end cities before the Update Aquatic and was having trouble with chests not wanting to combine when I was putting them away.

The issue has continued up to the current version (1.5.3).  The items would always stack with a partial stack already in my inventory but sometimes refuse to join with a stack in a chest.  This could happen to almost any item, from chests to cactus to torches to purpur blocks and stairs.  I would solve the problem by throwing one of the partial stacks on the floor, as they would stack properly when pulled into my inventory again.

Today (version 1.5.3) I noticed a new quirk when cutting down a 2x2 spruce tree with my silk touch axe.  I chopped through a few leaves on the way into the tree because it's a nice way to passively gather leaves.  Except they didn't stack.  I now have five seemingly identical spruce tree leaves that refuse to stack with each other in any way.

I think the problem with both issues is hidden data that causes the game to think that the items are unique and should not stack with each other, even when there should be no difference.  The only difference with the spruce is this hidden data is peristant, rather than being reset when thrown on the ground.

Does this happen with other items or just pumpkins?

I'll make a new report if you want.  This just seemed like the same issue, and I wasn't in the mood to have mine closed as a duplicate to this one.

Seems to be a duplicate of MCPE-32347

Ok.  Of course I searched "won't stack" and it didn't turn up the "don't stack" xP

This issue might also relate to MCPE-32152, in which breaking a chest incorrectly increments its Damage value. It may be that under certain conditions, other stackable blocks that are broken are getting their Damage values incremented. This would make them not be stackable with undamaged items.

It would be very helpful if someone could attach a world with normally stackable items that won't stack. That would allow me to look at the NBT data to see if their Damage values are 0, as they should be, or > 0, as I suspect.

Edit:
I agree that this sounds like a duplicate of MCPE-32347, so I intend to resolve this report as one. (I suspect both may have the same root cause as MCPE-32152, but I can't be sure just yet.) If anyone has a world they could attach as mentioned above, please attach it to MCPE-32347 instead. You might also wish to upvote and/or watch that ticket for updates.

This issue is a Duplicate of MCPE-32347.
