Cannot parse subtitles error for most of Serbian subtitles

[nagysifa]

Hi!

I am getting a lot of this error ( just for Serbian or Croatian subtitles ).

Here is subtitle that gets me this error ( it is a srt file originally, had to rename it for uploading ):
Allied.2016.1080p.BluRay.x264-SPARKS.txt
I get the error when starting the movie with the subtitle in the same directory, or after downloading the same subtitle, or if I try to load the same subtitle during playback of this movie.

Here is another subtitle, that gives me the error when starting the playback, but works if I try to load it during playback.
Just for testing purposes I tried to load this ( Finding Dory... ) with the previous movie ( Allied... ) but it wont load with that movie in any way.
Finding.Dory.2016.720p.BRRip.XviD.AC3-RARBG.txt

I am using VU+ UNO with pbnigma 5.1.0 . All the movies are played back from a network drive. Here is my subsupport config:

Thanx for your time developing this plugin!
