Support help with Apple Pages. Columns won't wrap properly around pictures?

Using Apple pages for the first time. Was surprised at how easy it is to get a good looking document BUT… now I’m incredibly frustrated with simple things. My main problem right now is that even when I make my pictures floating and indicate that the text should wrap around them- it doesn’t- when it used to wrap around my other pictures fine. I had to go to an older saved version of the document and paste these in because I accidentally erased a full page- this can happen rather easily I think. Anyway- now my pictures are not behaving properly- any tips? also is there any way to export a single page? that would also have helped immensely.
