Full storage of (infinity?) arrows in stacks of 2

so when I open the storage I can’t put anything in it, cause its full of arrows in stacks of 2. when I take 1 of those the game starts lagging and I just get it in the inventory. probable bug cause - once I bought around 1k arrows, but I didn’t receive any in my inventory (it happened like 3 months ago though, so today i took me time like 1h and took all arrows away from my storage). I think it got put into storage in stacks of 2 so even when I scroll down, I can’t see the end of the arrows put into the storage.
