Max/Current Energy Shield Mismatch Bug

I was doing a level 4 map when I leveled and chose a passive to increase my energy shield by 15%.

My energy shield maximum went to about 3600 but current energy shield was reading about 3750. I left the map and returned with the portal and then both read about 3600. When I logged out and logged back in later both my max and current shield read 3750 again.
