Weird ghosting on my art in affinity publisher

[Aj jackson]

So a couple of days ago I noticed that my art is duplicating within the page in solid black.  I cannot select it and it isn't supposed to be there.  I am not sure why this is happening but it destroying my entire project.  Please help!!  I have tried rebooting, installing the update and the file is still not showing properly. It is a shadow of one of my art elements but they shouldn't be copying in all black to all pages. Also, if I move something the whole page will have a grainy black shadow...I am attaching examples

Hi Aj jackson,

If possible could you provide a copy of the file so I can look into this further with you?

Thanks
