Podcast Episode Update

[BuckFiftyPod]

Hi everyone, 

I'm hoping to see if I can get some help. I have a podcast that's hosted on Spotify and I had an issue with the audio file on a recent episode. I had to go in to my host and switch out the file for a clean version. I did this Monday but the episode with the issue is still the one playing on Spotify podcasts. Is there any way to re-index so the correct one appears?

Also, does anyone know if Spotify keeps a copy of the episode on their end? I don't really understand how the old one could still be loading since it doesn't exist online anymore. 

Thanks in advance!
