So this problem of mine has existed for a while. Both twitch app and curseforge finds nonexistent wow folders and other game folders. Then the app adds them in the same list and scrambles it to look like the picture below. They were still named Retail and Classic 14.12.2020. But as of today 15.12.2020 they are names 1,2,3 etc.
The idea here would be to let us delete these extra game folders or let us at least rename them. I've seen this request many a time on different forums but seemingly it just gets worse. At least now since the names classic and retail went away and was replaced by numbers .
This issue is not present on a fresh/newly installed computer.
