Keys Not Sticking

I have several keys not stacking how they should and its making my bank take more space,
I have tried to sell them on the item market but even the market thinks the stacks are different items.
how can I stack them so I can use my bank spaces

 

This is a glitch. Keys from quests don't stack with keys from key guardians. Just throw out or use the quest keys.

 

You should be able to sell them on the trade market together (put them for a really high price if you don't want people to buy them), and then remove them to get them stacked.
For me this worked on and off but I'd try it before throwing them out

 

Selling them on the trade market didn't work
They're not from quests, they are from A long time ago

 

As in "skeleton dungeon" instead of "decrepit sewers"? Because those keys no longer work, and can really only be kept as memories.

 

I think he talks about how keys became broken after 1.20.

 

they have the same names and the same lore bits
