ok, quick question to anyone here with an Edge 500, do you have an entire horizontal row of pixels out about 2/3 of the way towards the bottom of the screen?!?!

if you hold down menu so the History, Training, GPS, Settings screen comes up, and scroll down to GPS, is the entire 2nd to last row at the bottom out?

i noticed it today on a ride, because i checked my Cadence during a climb and noticed that the part after the number looked like it said KPM, and i was like what the hell would KPM even stand for. after looking at it now, i just noticed that the top part of the R is that row that's out, and i was just wondering if i have a defective unit or it has something do with the way the screen on the 500 is in general...
