Files stop playing after adding subtitles

I’m running the Pro version of Infuse. Since the last major update every time I add subtitles to an episode of a tv show (with the function of infuse) the video file stops playing. It kind of freezes (the play/pause button remains on PAUSE as it was still playing) and I have to go back to the previous screen (the one with the summary of the episode) and hit the play button again.
After that it starts playing the video with its subtitles.

Is the problem known? Is anyone working on that?

Thanks guys!
