Exports full video, not cutting the range

Steps to reproduce

I'm baffled as to why LosslessCut stopped working for me. I've used it for a long time, but recently it stopped cutting and exports the full range of the video. It's happening on every video I've tried it on (all MP4/h.264/avc1). For example, it says it's going to export a subset of the video (say 00:03:49.726 - 02:23:37.235), but the export is the entire file. The ffmetadata file that it outputs says:

[CHAPTER]
TIMEBASE=1/1000
START=0
END=229725
title=

[CHAPTER]
TIMEBASE=1/1000
START=229725
END=8617234
title=

Used by the command:

ffmpeg -hide_banner -i '/Volumes/VidArkAlt/Stream Raw Recordings - 2021/2021-05-01 15-04-17 - MobReg Episode 5.mp4' -f ffmetadata -i '/Volumes/VidArkAlt/Stream Raw Recordings - 2021/ffmetadata-1674778901481.txt' -map '0:0' '-c:0' copy -map '0:1' '-c:1' copy -map_metadata 0 -map_chapters 1 -movflags '+faststart' -default_mode infer_no_subs -ignore_unknown -f mp4 -y '/Volumes/VidArkAlt/Stream Raw Recordings - 2021/2021-05-01 15-04-17 - MobReg Episode 5-00.00.00.000-02.25.44.682.mp4'

But I don't understand how that's used. It seems to be the right start/end point (in the second CHAPTER), but I don't understand how that's used by ffmpeg.

If I manually use ffmpeg using the command below, it works fine, so I'm just stumped as to why LosslessCut is not working.

ffmpeg -i `2021-05-01 15-04-17 - MobReg Episode 5.mp4` -ss 00:03:49 -to 02:23:37 -c:v copy -c:a copy `2021-05-01 15-04-17 - MobReg Episode 5 cut.mp4`

Expected behavior

Expected it to cut the video as specified.

Actual behavior

Exports the entire video. It even names it with the suffix 00.00.00.000-02.25.44.682, which is the entire video, instead of the specified cut segment.

Hi. This is because you are using the "chapters" export mode. please change it to Separate files

That was it, thanks! Not sure how that setting got changed.
