My very frustrating experience exactly!!!
When I select the image only, as daughter of the Frame, and add an adjustment, it just flashes briefly and disappears, nevere to be editable or re-locaed by dragging. That's a bug to me, even if 'designed." I will certainly take advantage of the solution offered here.
Later on, these misplaced layers are on top of the stack and then are carried forward when exporting to PDF for Print, though they look fine on screen. BUT the master page areas often, but not consistently, print in large black rectangles when proof-printing. I hope that Edit/Detatched will take care of this.
Publisher is splendid, often making my day! But these little things...
