Did you check the latest Lychee version?

Detailed description of the problem

When renaming a tag that is only changing the case of the text, it does not actually rename.

Changing "toronto" to "Toronto" does not.

I made all my tags lowercase by accident, tried to renamed them to proper case doesn't work.

1. Make a tag all lowercase.
2. Rename tag, change one letter to uppercase.

Fixed on edge.
