Podcast turned into TV Mini Series after adding a photo.

This mini podcast series (https://www.imdb.com/title/tt33094163) was originally marked as a Podcast Series (as it should’ve been). I later uploaded a photo, as this podcast had a video option. When I did that, it turned into a TV Series. It later turned into a TV Mini Series. I have deleted the image and have requested the tv-mini-series plot detail to be removed, and am worried that it will still remain as a TV Series. Could someone please turn this title back into a Podcast Series? Thank you!
