Can't unenroll from Beta

Hi,

Software Update is showing me Beta builds but doesn't give me the option to unenroll. I use Beta sometimes on some machine but on this machine right now, I don't want it.

Thanks,
Sean
I have a similar problem, Software Update is trying to give me a Beta build on my brand new M1 powered MacBook Pro that I received this afternoon. Never enrolled this device in the Beta program nd the usual unenroll button on the left doesn't exist.
I am also having this problem. The Software Update screen does not show the statement that my Mac is enrolled in the beta program and doesn't have the "details" link that would allow me to unroll the Mac. Even so, the OS is Big Sur Beta 11.2.

This is a problem when trying migrate the machine to a new M1 Mac because the OS is newer than what is on the new Mac. Migrating from Time Capsule has taken may hours so far.
I am having the same problem. Just completed a full reinstall by following the Big Sur link in the App Store and clicking, Get, which has got me to the latest version, but still asking me to update to the Beta in system preferences.
