Soul Core seemingly still applying after being replaced.

I slotted two Zantipis into my Solus Ipses to meet requirements then replaced one with a Zalatl. I have another Solus Ipses with only one Zantipi that, when equipped, makes me not meet the requirements for my shield but the Solus that once had two Zantipis does allow me to meet the requirements of the shield. I believe that the 2nd Zalatl may still be applying despite being replaced.

Uh, I'm a silly goose. My helms have different rolls on the "Equipment and Skill Gems have x% increased Attribute Requirements" line due to corruption.
