Can't move device from one group to another

[simpsonetti]

As described "nearly" fresh install, add some groups, some devices in and now one device (with an agent) should be in "OS with agent" but it never appeared there, so i add in an other group without agent. Than i want to move in the tight group but this won't work. No Message or something else.
What could i check?

You can't move devices between device groups of different types. So, a agent device group can move devices to another agent device group. Hope that helps.
