Locally saved replays seem to always end early

Hello!

I like to save replays of my Sim EC matches and rewatch/record my dogfights.

However, over and over again i find myself forced to use the “Server replay” feature as the replay I saved in the post-battle screen cuts out often at the 1 hour 20 minute mark or so - which is roughly the time I played, but it’s not actually aligned with when I joined (~20 minutes in, given it ended at 1:40 mins) and thus cuts out before the match actually ends.

Is there a setting I’ve set wrong? These are the only settings I see:
