Existing arrows are not showing up when stepping through a study or existing moves in the analysis board.

You are however able to draw new arrows and circles that appear temporarily, but as soon as you step forward or backwards they don't re-appear.

But, the arrows and circles and the board in general seems to be broken in more than one way. Sometimes pieces end up between squares, sometimes you can't move pieces at all, I've seen sometimes you can't even draw arrows when REC mode is disabled, and I've also been able at times to add two arrows of the same color from and two the same squares. So there is some bigger issue.
