Can you please export the page in System Monitor where you're seeing the incorrect disk space total and attach the .page file to this report?

I see that you weren't able to attach anything when you submitted this. Hopefully that was a temporary problem.

Thanks!

Thanks. Seems like the stats themselves are wrong here.
