managing towns and castles

Is this broken or am I doing something wrong, I'm playing as Vlandian vassal and I've captured and own many Sturgian towns, but Revyl and Varnovapol I keep losing those towns constantly due to rebellion, it has come to the point where it doesnt make any sense at all, I give mercy when I capture them and establish solid security from start 150+ garrison, but shortly after I lose loyalty even though I choose loyalty drift, yes I get I'm not the same culture but still it's really annoying that just as you capture the town in a short period of time you lose it to rebels, I don't see any sense in this, will this be fixed with full release or what?
