I think the problem is that it is not re-compiling after change, because the code doesn't change. Below is what I get when changing a comment.
Compilation started on 10/05/2022 11:37:01 with qualifiers 'cuk'
Class Custom.Utility.Functions is up-to-date.
Compilation finished successfully in 0.002s.
FYI, its not an issue for me anymore. I've been adding a space or something in the code to force a re-compile and it works. Mostly just annoying.

That did it. For my future reference its setting is:
