TV Shows - After adding a new series on my NAS, Plex is not bringing it in when I scan library in Pl

I could do that and probably will but I only started this and did on 10 of the movies is all so I thought I could just delete those and re-add them. I first have to upload back into my NAS and then scan the library to bring them back in. Doing the Plex Dance is probably the wise thing.

Thank you so much.
