The page number of the document (containing all the records I chose) doubled. Case 1: I use a excel file with 7 records to try the mail merge function on my letter (one page only), after production, I expected to see 7 pages, it turned out to be 13 pages. (all even pages skipped) Case 2: I used another source with 658 records, after merged, I expected to see 658 pages, it turned out to be 1317pages instead. (Again, all even pages skipped) Only the page number shown incorrect, the number of letters tallied.
Since you didn't attach examples I can't be sure, but merging an "odd pages" document produces empty hidden pages between merged documents for correct duplex printing. For 7 records and a single page, you get 7 pages + 6 hidden empty duplex pages => 13 pages. For your 658 records example I would expect a 1315 pages output, but without example data, I don't see a way to verify the bug. And please specify the earliest version you encountered the bug. If it's no bug, please close the report.
Set to NEEDINFO. Change back to UNCONFIRMED after you have provided the information and documents, if needed. Change to RESOLVED NOTABUG, if it was not a bug.
