Hello lekman100, and welcome to OpenStreetMap!
Andy from OSM's Data Working Group here.  Someone from the Ukrainian community has been in touch about these edits - mostly that's not because of your edits, but because of various "mechanical language changes" that have happened in the past.
What might be a good thing to do would be to say something over at the Ukrainian forum https://community.openstreetmap.org/c/communities/ua/66 explaining a bit about what you're doing.  You can write in English there - there's a translate button that allows things to be seen in other languages.
Best Regards,
Andy
