Release from cage still sees warning use undo

raster image placed with pictureframe then cage edited, when I move it I get ‘move released object from cage’, use undo, so I have lost the distortion applied, I undo the move, I run Release from cage command before moving it, then still get that warning when I move it !

tried explode and it says cannot explode single surfaces.


Strange, just try to delete control cage and see what happend when you move.
can you join 3dm ?

Have you tried this?
