BS.Player doesn't show any embedded subtitles after installing K-LCP

I am using BS.Player as my video player and after installing K-Lite subtitles will no longer load up.

This is how it looks, the mediainfo shows there are 2 subs tracks (MPC-BE would display subtitles from this file just fine), BS.Player will show just one track and call it "Undetermined" - normally it would show a language name, so it should show English

BS.Player is now using K-Lite installed LAV Filters, so maybe there is some problem there?

You can select the subtitle through the tray icon of LAV Splitter.

The fact that BS.Player doesn't show it is a fault in the player. Maybe they don't implement IAMStreamSelect functionality of DirectShow.

Thank you for the tip, yes, it works. Another problem I made myself was that during K-LCP setup I didn't specify the preferred languages for audio and subtitles, so when I did so, subs started to show up just fine (although I haven't tried any which doesn't have sub language specified yet).
