Video Issue

Hi, I’m getting a strange problem while watching a tv episode in my library that I’m not sure how to fix. Everyone once in awhile when I click play on an episode (mkv format) the show will play however it seems to play somewhere in the background. I can hear the sound of the episode playing and in the top right hand corner I can see a circle with the name of the with an arrow on it with the circle rotating.

I just can’t seem to figure out why it happens but more importantly, how to get the show to the forefront once it’s started playing, hitting stop on my remote doesn’t work at that point.. They only way around it is to quite Kodi. Is there another way? Is there a command key to bring the episode to the forefront?
