SD Pixel Aspect Ratio

I can’t share client material, but it looks like Topaz is reading something out of the metadata regardless of the source file resolution being 720x486. Attached is how the Topaz menu looks when I load two different 720x486. Both should be the 0.909:1 SAR, but one incorrectly reads as 0.89:1 SAR.

SAR_1_Incorrect
SAR_2_Correct
