Disabling Flatpak repos in Silverblue not working, need help

Out of curiosity, I activated via Software two testing Flatpak repos. But when I tried to turn them off, the buttons refused to respond as in a lock position (see screenshot below). I am talking about “Fedora Flatpaks (testing)” and “org.gnome.Geary.Devel from gnome-nightly”. Any suggestions how to turn them back off, please?

list the flatpak repos (remotes)
flatpak remotes

out of that list
flatpak remote-modify --disable "remote you want to disable"
or if you don’t want to ever use the remote
flatpak remote-delete "remote you want to delete"

It worked just fine. Thank you very much.
