I already try deleting all language in the [...] windows; and set english language alone here etc... (and a bunch of variations) but just to be sure i retested and it don't work at all. (FR ST are always taken even without any language, no matter what)
I already tried "new or old" mode parser/renderer and a bunch of other options to make it work... nothing changes. (French ST always loaded in the list)

Could it be a windows registry key than i can access/delete to rewrite the content? (because it seems like a info that can't be overwritten by anything)
An other idea: Could a very simple plugin be created (or exist) to select at least one language for audio track, and one language for ST to be "invisibly & manually" (like with the mouse in the menu, but invisible) selected when opening a file? (it could search and select the first track/ST with the code of the language selected in its options so ; maybe could be done with simple internal line command options etc...)
It could be an easy & distributable fix for this problem (without trying for hours to see where the prog or windows is doing a wrong thing etc...) and i don't mind setting that here (instead of ST/Audio pref) if i know that doesn't work there for me!

(Very sad that doesn't work even if the options are there, because heavy users like me will want that quality option for their many files from everywhere to play with their prefs etc... it is a must-have for an advanced "pro" player)
