Hi Robert,
You'll have to manually tweak the .dtl files to get all eight. Where do you want them to be displayed, so I can tell you exactly which files to tweak.
The issue with the Article free text #3 is reported here and has been fixed by making the change I noted in that bug on my installation: http://bugs.otrs.org/show_bug.cgi?id=379 However, the freetext entries for tickets 3-8 are not even being inserted in the database. I verified that the proper fields existed in my database and they are null for the tickets I've tested. When I look at the plain text version of the ticket containing those entries, I can see that the X-OTRS-TicketKey3 and X-OTRS-TicketValue3 entries are both there correctly, however only TicketKey/Value 1-2 work. I think this might be more than just an issue with dtl files, which seem to be set up correctly to display the values. Best wishes, Paul
