Hi there,
I had a similar issue, and i managed to solve it.
I know that the problem usually is exactly the same, but applying a different method to solve is the best way. Anyways, re configure every round game settings and postgame.
Meaning, if u have a device that manages, even better, deactive overrides, remove a few auto settings, and the last and the key to it, remove the battle royal to a classic or custom settings inside post-game.
