StaxRip - Frame mismatch

Hello, I keep getting frame mismatch...

Could somebody help me understand what I am doing wrong?

1st try

Again 2nd attempt:

WARNING: Target file has 609910 frames, but should have 739864 frames!
Encoding was probably terminated at 82,4% with a mismatch of 129954 frames!

Top is the AVI that StaxRip generates before muxing into MKV, bottom is source/input MKV.

3rd attempt
