PDF Export Shows Glitch

[jimhanus]

I'm exporting to PDF from DP7 using the commercial print settings. There is one layer of text on top of another of color bars. Where the edge of the top layer of text ends there is a step made in the color bars that shouldn't be there (see attached). I tried grouping first but the step is worse. Any ideas how to eliminate this? I know it's not much but it's not supposed to be there and I would like to get rid of it.

Thanks!
Jim
