Multi part episdoes: Not dispalying correctly

[SubsBware]

I've been trying to figure out how to format this correctly so it shows up properly in Jellyfin, but i cant seem to find the right settings.

I have a show where the first episode is a 2 part-er. But it shows up wrong in Jellyfin, but in different ways, depending on how i name the files.

1. I name it 
<Show> - <S01E01> - <Episode name> - <Part 1>
<Show> - <S01E02> - <Episode name> - <Part 2>

This causes it to list both episodes, however it lists them as Episode 1 & Episode 2

2. Naming it..
<Show> - <S01E01> - <Episode name Part 1>
<Show> - <S01E02> - <Episode name Part 2>

..Results in showing only episode 1, skipping Ep2 entirely, and naming Ep 3, as Ep2.

Both episodes have the same name, but they are different episodes numerically.

How can i format this correctly for Jellyfin?
