Bad religion traits for merchant/diplomat

What triggers the chance for that? Everywhere I've read mentioned religion over 80% and the presence of an abbey or higher, but I've seen the traits show up on agents trained in 75% Catholic towns with only a small church.

I think those traits are possible if the province you trained him in is too much of your religion(aka there is over X% of your religion). IMO those traits are BS since you want to have as much as possible of your religion in all of your provinces, and those traits impact your skill in all of the map(I'd understand that if he might be less effective if stationed in a province that is not majority of your religion but the engine does not allow that I think).

Yeah especially the diplomatic traits. The Pope doesn't like your diplomat because he's "too Catholic", really? I usually make a new diplomat any time I take a region with unfavorable religion score.
