Objects over auto-layout not showing in prototype or mirroring

I have a design done with auto-layout. When I place an ‘always-on-top’ icon menu at the bottom of the design over the auto-layout design, it doesn’t show up during preview or mirroring.

I use the hold Spacebar to place the icon menu.

Is there a way I am supposed to be doing this, to make this show up during preview?

Thanks for any feedback

Hard to say what could be wrong without the file link. The only reason I can think of is the objects are not inside of the frame — in the layers panel make sure they belong to the frame you are presenting.
