Subtitle page "Unselect all" button missing

[LV23]

I like the way subtitles are searched over the internet and that we could downloading them but unselecting all the subs available for a particular movie takes a lot of time... I just want to download a single subs not all 100 of them.

I was surprised that there is no "Unselect all" button in the page where subs are downloaded. If there are 50-100 subs available - please make the math about the time I will spend unchecking the 50-100 subs...

Rightclick in downloaded subtitles window and choose from the two options "uncheck all"
