IPTV record length?

Hey all,
I’m testing Jellyfin on the following system:
FX-8120, ASUS Sabertooth 990FX, 16GB, GeForce GTX 750 Ti (HW transcode enabled)
Ubuntu 20.04.1, Jellyfin 10.6.4-1

For some reason when I record an IPTV program from the EPG, I get a playback timeline that is 25+ hours long. The audio/video only plays back the actual record time…the reset of the timeline is blank.

I’ve found this in jellyfin status:
Current HLS implementation doesn’t support non-keyframe breaks but one is requested, ignoring that request

This is the end of the timeline:

Any ideas how to fix this?
