Movie runtime not correct in PMS

Was this file in any way manipulated? Was it produced by chaining several shorter files together?

Do you let the Plex Butler perform the in-depth media analysis at night? https://support.plex.tv/articles/202197488-scheduled-server-maintenance/

Are there several “versions” of this item? (different bitrates etc?) https://support.plex.tv/articles/200381043-multi-version-movies/

Or is it a “quality upgrade” for an older file, which had a lower bitrate?
I wonder if something changes if you Plex Dance it.
