errors in elevation totals on route tracker

I'll use this route as an example, since I'm pretty sure I hit reset elevation on there

3720 is the total spit out by the computer, but I can't see how that adds up to all that. 


(hint, it's a lot closer to 2,000 if you manually add up all the individual climbs)  I might have missed a few, but not 1700 feet worth.
