Ungrouping Page Numbers on Readymag Website

Hi, I was wondering if anyone knew how to ‘un-group’ pages on a Readymag website? 6 of my pages have somehow grouped, and instead of standard page number sequencing, these page numbers are as follows:
Page 45.1
Page 45.2
Page 45.3
Page 45.4
I can’t move any of these pages without moving the group of pages. Does anyone know how to turn them back into standard page numbers without the decimal point, for example:
Page 45
Page 46
Page 47
Page 48
Any help, would be greatly appreciated.
