/gamerule playerssleepingpercentage does not persist after all players exit realm

With the new game rule that is able to have one player sleeps on my Minecraft bedrock realm, it works perfect when I type the command in the chat. But as soon as no-one is on the server the command resets back to normal and everyone has to sleep.

I would like to add, my world is legit with no cheats on. So a command block is not in the equation. I've also asked command block experts and they said it could be a bug and to report it, so here I am.
