First step in Plex dance not working repeatedly

I’ve been following the naming convention to a t since the first time we had this conversation years ago. but every time I add a new show to the library, and then add the subtitles later, I have to do the Plex dance to get the subtitles recognized. it’s gotten to the point where I always have to keep the video files in a different folder until I’ve got the subtitles all fixed up, and then add them together in order for them to get recognized.

a while ago I switched hard drives, messed up my folder locations, so Plex read everything as new, and didn’t pick up the external subtitles for almost anything. until I do a Plex dance with them. and now, as I stated, the first step of the Plex dance has to be repeated more and more to get it to work, I’m just skipping it now, moving the files to an inaccessible folder, and then just deleting the show manually from my library before cleaning bundles and putting it back
