Retrospective record not working after a certain amount of bars

I have a session where retrospective record clears the buffer after 14 bars, bpm 88.
I’m playing within a cycle marker in loop, but the loop is longer than 14 bars.

Attached a screenshot of my setting. What does 10000 correspond to?

After taking the screen shot I’ve set the Buffer to its max, which seems to be 100000, but the buffer clears at the exact same point.
Any other with this issue?
