The storm devices do not work with "random movements"

The assault devices that Fortnite provides do not work with the “random movement” option. The only settings that work are the storm size and duration. The minimum/maximum movement is no longer taken into account from the 5th zone onwards. In addition, the zones always move back and forth from the 3rd zone onwards. There is absolutely nothing random about this and the players would constantly run to where they have just come from until the zone has closed. If anyone knows how to fix this problem or write a verse code for it, please let me know. Thank you
