Languages getting recreated after deletion

Went through language list deleting all except the 2 ones users should see. On last update all deleted languages are back again. How to prevent this happening? There is no way to disable a language so it is not shown.

I also want to delete all the languages except english and tamil.
Cant delete or disable the unwanted languages.

It is tough to scroll down through a long list of languages to change the language, every time.
