Run distance totals

I have been noticing that my monthly run distance in my log is incorrect for this month.  I only have 31 miles running so far and my data is showing 57 miles.  Is there something wrong with the system, have I added something somewhere?

I also checked Sept. run totals and it is incorrect as well.  I added the weekly totals for the month and it is still not adding up properly.  I like the bug totals but I would rahter know what I am actually doing rather than have a fasle number.

Thanks
