Are you supposed to lose city-state influence for tresspassing when they have "Defend us" missions?

First, no, I'm not Greece.

I have a city state which has a "defend us from barbarians" and a "kill a nearby camp" mission. They don't seem to care that my units are in their borders. I don't lose influence each turn. Is this intended? I'm using some mods but mostly quite light ones, no total overhauls like vox or nqmod.

It has been like that for a long time, idk if it's "intended" but i don't think anyone changed it with mods etc.
