Keeps Switching Episodes

I'm running Itunes 12.3.2.35 on Win 7 pro SP1.

I've been trying to listen to some podcasts and after a few minutes the software switches to some other episode from somewhere else on my list. I don't have to be on any other screens doing anything and it switches. At the top you see what it's playing. I have to click back on the episode below that I was just listening to and it continues where it left off. It's very annoying. 😠
