Cannot rename Coordinates prefix

Bug:
Hello, I love the mod but there is one simple issue. When I try to rename the prefix of the Coordinates item, it doesn't do anything. It reverts back to the original and never shows the prefix I want to call it.

Steps to reproduce the behavior:
1. Open the 5zig Mod menu and click "Customize Display."
2. Either create a new module or use an existing one.
3. Go to that module's settings.
4. Click "Items."
5. Click "Add Items."
6. Add the item "Coordinates" under "General"
7. Select "Coordinates" from the Items menu and click "Edit Prefix" in the bottom right.
8. Try to rename the prefix and click "Done."

Expected behavior:
The prefix to be renamed to the name I set it to be.

Thank you in advance.

Look for the Coordinates item class in the codebase, likely under a module or items package. The prefix editing logic is probably in a UI handler or configuration manager. Check how other items handle prefix renaming to see the pattern. Test by running the mod in Minecraft and following the reproduction steps to verify the fix.
