Expected Behavior

If I am able to export annotations from the task that contains 1 job, I have to be able to export annotations from the same task composed out of N jobs. Now it is impossible. Checking internally, I see that for some reason, the last frame of the track (outside=True) for several tracks are doubled, which is actually produces this error.

Possible Solution

No response

Context

I can provide annotations if needed

Environment

I see this both in 2.9.2 and in app.cvat.ai
