Generally, when we clear the Resize AutoShape to fit text check box on the Format menu, we can move the shape/object in PowerPoint slide.
First, may I know If you Choose View>Master>Slide Master Layout, can delete them there. Also, please confirm does this problem happened to specific PowerPoint file, it will help for us to narrow down your problem.
Meanwhile, if you don’t mind and if it is convenient for you, could you please send copy of your document file to me so that I can look from my side, and I will check this behavior and help you to fix and verify the result with you.
