Conversion incorrect and not editing correctly

I opened my Bookshare (BSD) glidepage. This is a page I created for my school district. The conversion deleted a photo and added in random add in boxes. I tried to add a photo to replace the missing one. It put the image below where it should be along with a text or photo side box. When I tried to delete it, it said it was going to delete the entire glidepage. When I tried to delete it again, it said it was going to remove text boxes and four images.
