Writer: Mail Merge (toolbar) ignores last row of spreadsheet when e-mailing

Build ID: 7556cbc6811c9d992f4064ab9287069087d7f62c

-UPDATE also confirmed on macOS version on Sierra 10.12.4

Doing a mail merge via a connected .ods spreadsheet

When sending to e-mail recipients, the merge fails to send to the last recipient, i.e. for a spreadsheet with n rows, only the first (n-1) rows are sent. (tested: 2 rows, 3 rows)

Also, there is an indication that something will fail, because the option to Send [] to [] is incorrectly populated as

Send 1 to 1

irrespective of the number of contacts in the merge. On working earlier versions, the Send is correctly populated
with all the rows at this point.

Is this fixed in any earlier or later version ?
