Donation Failed Page Won’t Delete

I now have “donation failed” and/ or a “donation confirmation” pages that will not delete. When I try to delete them from the Pages tab they do not delete and keep re-appearing. Sometimes several appear at once. I have set some of them as drafts so they don’t all appear on my home page. I have no idea why this is suddenly happening. I deactivated paypal donation plugin, which was likely automatically downloaded. If I go to Appearance – Menu – there is no option to delete them there either. My host provider, Bluehost, said to contact you to get this fixed. Please help. Thanks.
