Sorry i never saw this. This happens on ALL services that have multiple subs but mainly i use Amazon Prime Video and Netflix.
This is a UI/Settings issue so there is no need for a log file for downloading.
Let me try to explain better:
When selecting a show to download, if there are multiple audio or subtitle tracks, StreamFab will set one of the tracks as the Default track. Usually it will be the last track selected.
When StreamFab pre-selects the tracks, it does it in Alphabetical order so because i select English, French, and Romanian, Romanian is ALWAYS the default subtitle track.
Luckily, we can select the default tracks in the Download selection pop-up by putting the little orange triangle next to the tracks we want to be set as the default.
That's great but sometimes, we can forget and also, to set a track as the default, you need to Click the drop-down, scroll to the track you want, unselect it, click to the left of it to make it default, then select it again. Lots of clicks when it should be a setting.
I noticed that it seems like it IS a setting if you look at the pre-selection settings but once you set the default track and click ok, it goes back to nothing set as default, which means it will once again put the last language as the default.
Setting the Default pre-selected Subtitle:
Click ok, go back to see and now the triangle is gone:
Go try to download something, last track selected is the Default:
