@lancegspencer - I’d suggest you start with this tool Home · ukdtom/WebTools.bundle Wiki · GitHub
FindMedia. Makes it possible to locate medias, that’s either missing from the database or from the filesystem
To Ignore files you can check this help article - https://support.plex.tv/hc/en-us/articles/201375253-Excluding-New-Content-with-plexignore
This is a good place to read up on (it is linked in the WebTools user manual too) - https://support.plex.tv/hc/en-us/categories/200028098-Media-Preparation
And as always, I usually instruct users to scrub all their files in Filebot first, before presenting them to Plex - https://forums.plex.tv/discussion/191687/plex-naming-schemes-for-filebot/p1
If you have already got an incorrect match on an item (due to bad filename), you might have to do the Plex Dance on it - https://forums.plex.tv/discussion/277433/the-plex-dance
