Can't create Project access token

GitLab SaaS, Free tier.

If Project is standalone I can create project access tokens just fine. But if Project was added to a Group - I can’t create Project tokens.
I’m aware that -
"You can use project access tokens:

  • On GitLab SaaS: If you have the Premium or Ultimate license tier, only one project access token is available with a trial license."

But it works just fine until you add this Project to a Group. And once again - I don’t need Group access token, only Project access token.

Is this an expected behavior?
