Episode parts are picked up as versions

[Iskelderon]

https://jellyfin.org/docs/general/server/media/shows/ lists such cases as 

Code:

│      ├── Series Name A S02E03 Part 1.mkv
│      └── Series Name A S02E03 Part 2.mkv

 but in my case, these are picked up as versions instead of parts:

Code:

"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E02 - Love and Anger Part 1.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E02 - Love and Anger Part 2.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E03 - The Queen's Sacrifice Part 1.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E03 - The Queen's Sacrifice Part 2.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E04 - So Close, So Far - Part 2.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E04 - So Close, So Far Part 1.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E05 - The Friend Found Part 1.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E05 - The Friend Found Part 2.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E06 - The Innocent Part 1.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E06 - The Innocent Part 2.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E01 - The Perfect Day Part 1.mp4"
"G:\Video_other\I\Don Matteo (2000) [tmdbid-21220]\Season 13\Father Matteo (2000) - S13E01 - The Perfect Day Part 2.mp4"

Putting in a "-" separator between episode title and "Part" doesn't seem to make a difference to Jellyfin either, already tried that.
IF it makes any difference, I'm using the Jellyfin path preset in Filebot.

Probably just a tiny difference causing the problem, so it would be great if anyone could point me in the right direction.
Thanks in advance!
