It's an issue with microsoft accounts.
You're not on Java stupid.
This is a current bug with microsoft accounts. Log out and use a mojang account.

You do it by left clicking. Can't further help you.
Are tile drops off? Are you on Bedrock?
This must be modded.
Nope, you can't.
Ok, click I understand, or yes, whatever it says
This isn't a bug. I don't know what you want to happen, but this is a feature.
Not a bug

Go to instalations, click modded.
Are tileDrops off?
Nope, this still makes sense. Once you click the respawn anchor, any logs of your bed being the spawn are deleted.
Hmm, must be something with the wool positioning. Hard to tell if this is intentional or not.
We need more context. What device? What version of the game (1.15, 1.16, etc.)? Are you logged in on a Microsoft account?
