Revit 2018 can't move simple model group

[Anonymous]

I'm trying to move the model up (Z direction, see attached screenshot).  It is a family environment. I get the following error massage:

"Can't move these elements at the same time. One of them is restricted to moving in one direction while the other is restricted to moving in a conflicting direction".

How do I get around this problem?

Many thanks in advance.

... and then the vertical ones

... and then any other to the right position
