Events sheet are read top from bottom. So the tick you activate again your group, the whole group actions will be executed starting with the very first on top.
Perhaps you also want to have a look at the new "Wait for signal" system action that will allow you to only have a certain event run when a certain tag/signal is used/sent.
It sounds like you have an issue in your events organising and you should detail precisely what you're looking to achieve and provide/attach a capx so that we can help you "cut" and organise the events in the most efficient way.
Without your project to ponder about, it's guesses and shots in the dark.
I hope this helps.
