Incompatible item list?

All of the conditions are met, they seem to refuse random items and say it isn't a good fit. I have a theory it might be related to their personality which is why I wanted to put the section in, it would also save people from buying items for their partner that they won't accept.

The items were not light or heavy armor, were not personalized, and were in the main inventory. I've also noticed a strange issue where my partner would accept certain accessories that my friend's partners would not.

I have made up a template in my sand box if anyone wants to see (though keep in mind there is no accuracy to the template, it's just an example).
