You might inadvertently have triggered Plex to treat the videos as “stacked files” (1 movie split across different files). Adding a suffix like -disc1, -pt1 or -dvd1 is part of the official naming schema and results in Plex considering the files are different parts of the same movie.
You should see that the item listed in Plex has a longer runtime than that of the 1st item.
That being said… stacking files can be tricky as not all client apps support it.
- if this is separate files and you want Plex to treat them separately, try to review your file names (e.g. include the
Disc 1section before the release year (e.g.Concert ABC - Disc 1 (2022)). - if you actually like the idea of the videos playing in sequence… you might want to consider looking into merging the files (less of a pain in the long run)
