Reply To: Merge issue with large curly bracket

That is officially a truly weird problem.
Do you see the curly bracket on screen? I don’t see it when I open your INDD file. So it occurs to me that maybe it’s a font on your system. (That still doesn’t really make sense, but I’m stretching here.)
The other thing that doesn’t make sense to me is why this information is on the master page of the document, instead of the document page.
