Why did porsha disrespect Kenya in s5?

I know yall hate Kenya but im talking about when Kenya was going to the hosea Williams Event in season 5. They barely interacted before but still porsha was Like 'miss ....America....uuuh..1993 or Something...' Like rewatching it seems weird to invite someone and Not even know their Title or the year they won? I can excuse the usa\america Thing but Like..the way she presented her was VERY disrespectful. Idk If it was meinst i would make Sure to present any guest with Respekt And knowledge about them.

And i would get If it was later on cause they were beefing but at that Point they barely Had any contact. Do yall think Something happened behind the scenes ? Cause why she do that?
