I can't really do anything with a list of metadata. A few select samples would be helpful. (Also, Aspect Ratio seems to not be in that?). Don't need 0.00 samples, thats just a bug and will be fixed.
In general, its not making up data for aspect ratio, so if its coming up with a value that is not 0.00, then that is based on data from the file. In the simplest case just w / h, but many files also have an aspect ratio beyond that for anamorphic rendering. So if you have a file with the dimensions of 720x576, which has a natural aspect of 1.25 (w / h), then something is transforming it to 1.00, that value is not an accident.
Sometimes there can be conflicting info in a file. The video stream says one thing, the container another, and which value to give priority is a long debate. I'll double check the preference matches what playback uses.
A sample would of course let me make sure.
