Automatic numbering in book not working
Hello everyone,
I have a created a book with many different documents inside. For the moment is still missing the document 3 and 4 not writing yet.. 
The first one (0 Structure) is in Roman numbers and all the others docs are in Arabic numbering (from 1 Partie to 7 Structure).

In the Arabic numbering documents, the first one is manually defined to start at 1. Then I wanted that all the others pages of the different following documents be automatic (because I may add new pages in the documents, and I’ll also add the missing documents soon). The automatic numbering is working for the document 2 which starts at 35 as supposed, but for the two next documents it should start at 79 (not 45) and 87 (not 9) and I don’t understand why ?
Thank you in advance for your help,
