Papal standing?

I’m struggling with keeping papal standing in check. It seems papal standing decreases whatever I do. I’ve built churches, sent priests to convert, completed missions. The only thing is I am at war with some catholic states which m trying to resolve. I’ve heard some say this mechanism is broken? Any tips? Thanks

I don't play that mod BUT: "I am at war with some catholic states" sounds like it should be a big thing. You may build churches and all, but they do too. And since you used plural, I would be surprised if the Pope wasn't disappointed.
