Don't edit/change NFO file info?

[McCordRM]

Hey, folks! I'm moving away from Kodi and have a library that is fully custom. I've gone through every NFO file and curated the info inside of it. I have also added <lockdata>true</lockdata> in each file. Inside Jellyfin, I've checked the box for "Lock this item to prevent future changes", and unchecked each box underneath it to keep those sections from being changed.

However, Jellyfin keeps making changed to the files. How do I prevent that? Thanks!
