I notice when I was recording my lecture today that the time left remaining in the stats dock went into the negative numbers with well over 185GBs of storage left.
It looked like the number overflowed from positive to negative numbers, the negative number was ridiculously huge (small).
When I moved the stats dock window it corrected its self to displaying positive numbers.
When I say moved, I mean I took the window and moved from the bottom of my screen to the top of my screen.
I was going to take a screen shot but I didn't realize that moving the window would fix the issue.
I am using stats in View>Stats not the one in View>Docks>Stats.
I'm sorry that I can't provide any more information about the bug.
