MakeMKV causing audio sync issues

Does anyone know what would cause MakeMKV to rip a DVD that was originally 29.97 FPS to 29.761 FPS?
I de-interlaced the first DVD of 4 from the 1st season of the 1988 television show of War of the Worlds using QTGMC in AviSynth+ via VirtualDub2 and even an FFmpeg batch filed script after ripping it with MakeMKV with no problem, but on this 2nd DVD it won't rip it correctly, so when I de-interlace, it throws the audio completely out of sync.
Here's the media info from the ripped from DVD MakeMKV file:
