got the exact same issue.

playing the same realm on Win 10, Xbox One and Android. 

Same notes from a previous ticket: 
I have the same issue. I did some testing since I knew I had another bell in a chest.

I had a bell placed in a made up village. I removed the bell and then it glitched. I couldn't replace the bell on any objects and I couldn't move it within my inventory. The glitched bell was part of tool bar as a selectable/usable item, and not part of my stored inventory on my character.

If I put the glitched bell in my hand I couldn't interact with anything (example: opening doors/gates, or opening chests). If another item was in my hand I wouldn't have a problem.

I went to my chest and tried to stack the bell onto the glitched bell. It didn't show that it stacked but it did. I still couldn't interact with the stacked items. I could separate the stacked bells into to different slots in my inventory. The glitched bell would not move from the slot it was currently occupying. The second bell worked fine. I could place it on objects and use it as normal.

The glitched bells remains glitched in it's item slot. I'm unable to place or drop the item. If I spam the bell while trying to place it, the villagers seem to react to it, even though it's not placing, as though it's being rung. At one point I did get it to ring while it was not placing.

If you try to swap a different item, it glitches the other item into it. The number of that item turns yellow, like the bell and then it seems to show you selecting both the bell and the, now, invisible items you placed with it. Even though the invisible item doesn't appear on your cursor, you can still drop it out of your inventory with a drag and drop.

 
 
Now I've found that this bell will dupe items that go into your off hand inventory. The bell is not stacked (at least I think it's not). In windows 10, if I long right click the bell and have it select "two" bells, if I select something that goes in the off hand of my character, it will dupe that item into the off hand. I've confirmed that it works with totems, shields, and maps.

You cannot dupe items that will not go in your off hand.

I have the same issue on Win 10.

I'm playing on the Nintendo Switch, accessing a realm for my family, and I am experiencing the same problem.  I want to pick up a bell and move it to another location to change the village's gathering spot.  Thing is, each time I pick the bell up, I can't put it down.

I can't place the bell on any surface.  Attempting to results in the bell instantly vanishing and returning to my hand in the inventory.  If I try to "drop" the bell and throw it on the ground, it again returns right back to my hand.  I also can't move it into my inventory.  If I try to, it returns right back to the active items bar (I forget what it's officially called), thus taking up a spot that I can't use for anything else.  This all started after the Realm was updated to 1.13.0 and after I updated my Switch version to 1.13.0 too.

The only saving grace I've had with getting rid of that bell is the fact that ANOTHER reported bug here on site discusses the "time warp" where much of the progress made by a player is undone as it reverts to a point in time that could have been several minutes earlier.  Thankfully, this means that the bell goes back to where it had been originally put.

Same issue here! Super annoying!!
