Canon 5D Mark II - Shutter Count is Wrong?

[Deepsnoozer]

Hey guys, got a Mark II here, i bought it second hand and the owner told me this has been used mostly for video, and less than a few K shots had been actually taken.

The thing is, my shutter count was 24k (now 25k since i took almost 1000 pictures in the last days) 190000 or so + 170000 or so.
What?
Would these two numbers add up to be  in the high 300K's?

here's photo of what i am saying


Is this a bug?

Substract and the result is 24966, which is 25k.

How do you know 25k is the correct result?

Found a Windows only app  here: http://www.learningvideo.com/shutter-count-3/

Runs fine in W10.

My ML Shutter count says, 17k = 14267 (matches the app) +2708
I'm assuming that the second number is the number of live view activations but I could be wrong.
