Items getting erased on Minecraft realms after world download.

Hi, so there is this current bug on Minecraft realms. When I join our server and play everything is ok and nothing happens, but when I download the world to single player all my player data gets reset meaning all my items get erased upon loading the world in single player. I wanted to see if anyone else noticed this bug and that mojang would do something about it. This has NEVER happened before and it feels like no one is noticing it and mojang hasn’t addressed it. I’m playing on Java 1.20.3
