Delay in the recorder when using Timeline

Hi, I am trying to use the Unity Recorder to generate a sequence of images from a Timeline track, based on an interval of frames (from frame 0 to frame 91 for example). The issue I'm facing right now is that for some reason the first frame of the track is ignored, and then an extra unwanted frame is recorded at the end, essentially shifting the entire track by one frame. So instead of getting an image sequence from frame 0 to 91, I get it from frame 1 to 92, which is a big problem for me.

I suspect that maybe the recording starts a bit later than it should after the editor enters Play Mode for recording, but I'm not sure.

Is there a known solution to this? I have already tried several different settings in the recorder, but no luck.

I'd appreciate any help!

Thanks.
