Strings catalog not removing unused strings

I have some formatting strings that got in my string catalog, e.g. "%@" or "(%@)".

However these strings are no longer used in my code anywhere (searching "In this project" in Xcode only matches the entries in my strings catalog), but Xcode does not remove them.

I tried editing the file in a text editor, removing them manually but they keep coming back.

Any solution for this?

Xcode Version 15.4 (15F31d)
