Problem With Round System Functions

Hi, I have a trouble with round system on my map. I have created a system where players play small minigames and at the end of the round they fight each other on a landscape with bunch of props and bulidngs (battle royale style where players can build and destroy trees for materials while strom is closing in). I have a setting in Island settings that after last man standing the round ends. Now here is my problem: when you load into the next round - the storm that was closing in is still active (even in lobby and other places of the map), and also all the props (trees,walls) on my battle arena are still destroyed, same with some devices that did not reset. I need a way to somehow restore all devices and enviroment each round.
I though thats what happens when I was setting up the rounds ( to treat each round as if I load into the map for the first time). But there are many persistent devices and props from the previous round.

How can I fix this?

Having rounds is not necessary, if anyone knows about better system (like resetting everything with a trigger and basically let the game go in a circle forever) I would love to hear your suggestions.

If only there was a setting to make each round same as the 1st one wihtout any perstistency from the previous one.
