I am using data merge for a few years without a problem. The last months I have nothing but problems with this tool. It is mixing up my data fields in the layout page so it is totally unusable.
The strange thing is dat the preview where you can browse in the records is reading my data correct. If I execute the data merge with multiple records all data is mixed in the layout.
Please Adobe! Fix this thing as it is very important in my workflow.
Working with the latest Indesign version 2015. Tested on Mac and PC, with same result.
Try to create a new file, copy your field placeholders and paste into the correct positions and run without preview.
Thanks a lot!! It worked that way. Saved me a lot of work.
Adobe still has some bugs to fix in the data merge because this is not a logical way of working.
Again, thanks for the tip.
Edit: If I remove the A-master page then the problem is solved. So data merge with a master page is not working correctly. I hope Adobe will fix this soon.
