TL;DR I’m grateful for translations by translators. But translating everything causes icons to break. Ubuntu MATE 20.04 has several broken icons and most of them are fixed in Ubuntu MATE 20.10 already. Advice: Please do NOT translate the ‘Icon’ text, just leave that translation blank (""). Copy/pasting the English text will cause superfluous lines in .desktop files and might cause additional work later (if the original name is updated, you will need to copy and paste that string again).
