Decal Gizmo not visible

Hi everyone,
I have a problem, that I cannot see the decal gizmo in UE4, this means that after I have placed a decal I cannot go back and select it for editing.
Any suggestions for what I may have turned off, or what shortcut key I may have used accidentally?
(I know G should turn gizmos on and off, and it works with everything else in the scene, just not the decals)

Hopefully someone can point out the obvious fix that I am missing :slight_smile:
