Even though you don't like already existing descriptions, the problem of case conversion has been handled in the FAQs:

> How to change upper/lower case of tag fields or filenames? Create a [new action](https://community.mp3tag.de/t/actions/967/2) in an existing action group and choose Case conversion as action type. Field determines which parts of the tags/filename should be changed. Case conversion determines how the upper/lower case of the field will be changed. If you want for example mark chars after a left parenthesis or a hyphen as the begin of a word, enter the respective char under Words begin from/after any of.

t would still be nice for us sitting far away from your PC to get some description of what you have done which led to the described result.
