Hi @Dan C,
Suspected PICNIC...
I started from a new afpub document (v1) and manually added my existing masters (C+P layers) from an old small file.
I split my Masters files into 2 files - with data merge and non-data merge masters.
The Data Merge file generates the pages to be merged. and there are only 7 masters in this file: 5 masters make a single page 2 masters make a month's worth of pages (each month is merged to crreate a new merged month file) The non-merged masters file is the basis of the final file.  This file has loads (>20) of masters - headers, footers, month pages, etc once I add the merged pages (for a month), I add the relevant headers, footers, etc. I have sucessfully merged and added 157 pages (so far) and the file size is a tiny 2.9Mb
I think the following may have caused my reported issues:
my original (wing it) workflow of having all the masters in one file and merging with this repeatedly on the fly editing of a master (either in original or merged file - they look the same) may have caused issue 2 when the paged were added from the merged file. Cheers,
Caleela.

Hi @Caleela,
Thanks for your report!
I'd like to request a copy of your Publisher documents and Data Merge source file, so that I can further investigate this issue here.
Can you please upload:
A copy of the .afpub file pre-merge with your Data Merge layout on the master page, The Data Merge source file The .afpub file this creates post-merge ("untitled.afpub") The .afpub file you have merged the Data Merge file into, where a duplicate Master page is created https://www.dropbox.com/request/A6ZFirdRWsVpWcH5l2fJ
Once uploaded, please reply here to let me know - many thanks in advance
