DWA how to select when invisible

[ntellery]

I have a DWA (CWA?) with inserted objects (door & window styles). 
The DWA frame is invisible so I cannot select it and I cannot work out how I've done it.
Is there a way to make the frame visible or selectable. I need to delete it from the drawing.

Are you sure there is anything there?  Using CTRL+A to select everything, there is only one Door/Window Assembly listed.  When the Doors (four on the left, six on the right) and Windows (four) where you think there is a Door/Window Assembly are selected, they display a Location grip; a Door or Window anchored to a Door/Window Assembly does not display a Location grip, as it cannot be moved independently of the host Door/Window Assembly.

Using QSELECT to select all Door/Window Assemblies also only finds one.

Thanks David.
I've checked in the original file and while the left door has location grips, the right and the window don't so they appear to be anchored within an object. If I delete them they just reappear later (not immediately).
Somehow in trimming the file down I might have lost the parent object however these components stayed.
Using SelectA and deselecting everything I can see in model space I account for all DWA and CWA so this is not one.
I have had this recently with a CWA is use for cabinet doors where rogue doors keep appearing after being deleted and thought maybe this is the same parent object with the frame turned off or a turned off material applied but I think I have discredited that.

Looks like I will just have to put up with it. It may well be a glitch.
Harkens back to my 'ghost walls' from years ago.
Thanks for taking a look.

No solution.  The file I posted does not represent the problem accurately.
