Hi sth-bzouggari, welcome to the community.
So if you search for and locate one of the computers that is part of a group that you cannot see, what does it show in the Manage Device column on the right after selected the computer? Does it show the group name that the computer is part of?
Indeed, when I search for a device in the search bar at the top, I find it.
But when I look in the device column on the right, it indicates that it's not in a group, although I'm sure it has already been classified in a group. And when I try to put the device back into its group, I can't find it
