Chaos item incorrect specs

I I acquired the WUSHE NAK PA chaos armor as Pants last week and I fully masterworked it all the way to level 12. It is single GA on percent Ultimate Damage and the fully masterworked value is 319%.
This afternoon, I acquired a “normal” WUSHE NAK PA glaive with the Ultimate Damage GA and was shocked to see the normal value for that Ga is a whopping 435% BEFORE Masterworking.
That seems totally wrong, I thought the values between normal and chaos are the same for GA attributes.
Likewise, all the other attribute values except for the aspect are seriously undervalued on the chaos item compared to the normal.
Is this a bug, or am I not understanding the chaos gear concept? Why would the attribute values on a chaos item be so much lower for GA and non-GAs versus their normal counterpart??
I have images if you want to see them. I can’t find a way to attach them to this report on this mobile app, but I can send them to u via text or email if you’d like.
Thanks for your attention.

Yeah I have similar issue! i got mine with GA on supremacy and it only shows +2. master work 3 times and i have +3
