I have been running into an unusual issue that I can't seem to figure out a solution to. I am trying to prepare a disc image for a personal bluray project, but it keeps failing and giving me the same error message.

MUXComp:Validating error. --- The 'number_of_PlayList_marks' element has an invalid value according to its data type

I have checked to see if there are strange characters in place, redundant spaces, title limits, etc, and I just have no idea what to do. Has anyone else run into this problem, or does anyone know what the issue is?
