Only Forced Subtitles dont activate on start

When i set "only forsed subtitles" in lav splitter and play video that have forced subtitles, subtitles are set to "no subtitles".

How are your preferred languages configured in LAV Splitter?
Does the desired subtitle have a language shown in the selection menu?

It doesn't matter if i set the same language as forced subtitle in the video have (rus) or clear language to none, it starts with "no subtitles".
My current solution is to set subtitles on "Default".

Why does it take so long to fix? I just want only forced subtitles. It was working somewhere near 15.4.0.

Can you give a link to a video that I can use to replicate the problem?

I dont think that its exact video file,because i watched about 30 different videos with the same problem.
Thats what i get by default in lav splitter: Advanced rus:rus|df,rus:*|df,rus:off,*:rus,*:*|df
with that settings it activates only default subtitles in russian.
When i change to: Only Forced Subtitles or Advanced rus:rus|f,rus:*|f,rus:off,*:rus,*:*|f
then i get no subtitles when i start video, but i can change to whatever i want manualy and it works.
Maybe its settings that i choose during instalation? I use standart installer, cheking use codecs only for mpc-hc and use only 64 bit components, use internal audio and internal subtitles with russian language.
Windows 7 SP1
Videos are mp4 avc with mkv extension.

It is possible that the subtitle track is not actually flagged as forced. It should show "[forced]" behind the subtitle name, similar to how it shows "[Default]". Some videos only use "forced" in the title of the subtitle, but don't flag it as forced.

You can check with MediaInfo if the subtitle track is really forced. Copy the MediaInfo log here so I can see too. Maybe I can modify LAV Splitter to also look at track title.

Yes,you are correct.

Thats from 3 different videos.
I just want player to activate only non full subtitles.

Add this:
*:rus@Forced

This will select Russian subtitle that has "Forced" (case-sensitive) in its title.

Thank you.That worked.
