My Question or Issue

When I listen to a music playlist and I see that a new episode of a podcast came out, I like to add the episode to the queue. So that when the current song ends, the new episode of the podcast starts. This works pretty well. However, when the podcast ends, it changes my Next Up completely by adding all podcast episodes to it. This is unwanted behavior. It should continue playing my original playlist. 

I made a GIF with the problem occurs. (See attachment or https://i.imgur.com/CLy7ocW.gifv)
