I just edited this post, and I created a new tag by mistake.
I was about to add a new characters but then realized it wasn't necessary and went on to delete the
char that I had just begun typing in the tab bar.
The existing tags reverted to their original display translation and meaning-in-context, so I thought everything was good, but after I hit edit, the system actually created the tag with the extra characters as if I never deleted them.
So now there is a meaning-in-contextchar tag.
How can I delete this tag? I think I don't have enough privileges to do that...
