How to update Catalina beta without updating to Big Sur?

Hi!
I'm currently trying to update my Mac software to Beta 4 of Catalina. In Preferences > Software Update, my only option is Big Sur.
My first attempt was to remove the beta profile, go to the downloads section and reinstall the Catalina beta profile.
After a restart, still it only shows the option to update to Big Sur.

Is this a bug? Any ideas?
PS: No, I don't want Big Sur.
When you open Software Update, there should be some text in blue that says something like "additional updates" or something like that. It will be below the Bug Sur entry at the top. Click the link to reveal a sheet showing other beta options. Just did this today. Sorry, no screen shot.
