Minecraft demo bugs?

I'm currently playing the Minecraft demo. It struck me that monsters don't attack me and villagers don't want to sleep in beds.

Is that because of the demo of the game? Will the bugs go away when I buy the game?

Java or Bedrock?

Yeah should be a bug

In the full version I haven't seen anyone with this bug

Which monsters are not attacking you btw?

For example, spiders don't attack you during the day

And did you play on Java or Bedrock?

Java

I play the Java version.

Skeletons target me, but zombies, for example, don't.
