Trying to delete downloaded videos

I’m trying to improve battery life on my iPad Air 2 so I went to settings>general>iPad storage and saw I have three downloaded videos from Netflix on my iPad. I can press edit at the top but I can’t delete them. When I go to the Netflix app, there’s nothing in My Downloads (in fact I distinctly remember deleting them in the first place!) Does anyone know how I can get rid of the videos from my iPad? Thanks in advance!
