I tried to open your project but got a message that one of the plugins isn't installed, but it says that it is the Text plugin that is missing. I'm using R92 and the standard text plugin is there. What are you using?
Anyway, the first thing I was going to try was to move that last condition (invert is overlapping family1) into a subevent and move the action to the subevent like so:

I think that will do it.
