Plex TV Series - two different one displayed as duplicate epsiodes

Plex TV Series - two different one displayed as duplicate epsiodes - they are different series and different episodes with different unique names -

rsg-miss-fisher-s01e01-1080p.mkv

and

Miss Fishers Neue mysterioese Mordfaelle S01E01 1080p,mkv

what to do that they are being recognized as different series

thx

Name it like:
Miss Fisher's Murder Mysteries (2012) {tmdb-43078} ← Show folder
Season 01 ← Season folder
First Episode - S01E01 - .mkv ← The episode

Ms Fisher's Modern Murder Mysteries (2019) {tmdb-86847} ← Show folder
The rest like above

thank you! one more question - how do I get the ID from tmdb?

got it - it was easy - directly in the URL of tmdb

OK… I renamed them - some are working but:
/volume3/DATA3/Serien2/Kim Possible/Season 02/Kim.Possible.S02E06part01.Rufus.der.Hundestar.DL.German.Dubbed.1080p.WEB-DL.AC3.h264-SAMSON.mkv
and
/volume3/DATA3/Serien2/Kim Possible/Season 02/Kim.Possible.S02E06part02.Rufus.der.Hundestar.DL.German.Dubbed.1080p.WEB-DL.AC3.h264-SAMSON.mkv

are still being treated as duplicates - what am I doing wrong?

thx

You are still not following the naming guide!

When said, they are to be considered 2 parts of the same file

Edit: Please do NOT ask the same question multiple paces!
