Duplicates appearing when I drag an image

I have been using Corel for years but have just experienced a new problem.

It seems to happen every time I import an image to Corel (although this may not be the reason t is happening).  As I click on and drag the image to move it around the page lots of duplicate images appear as if shadowing the original image and I can't move it without ending up with hundreds more on the page.

Any ideas why this is happening and how to stop it please?
