V8i SS4 Dimension Text Orientation Changes after Copying from Reference

Dimension text orientation is fine in the reference file but when something is copied using a fence or the selection tool the text orientation goes vertical.  Some users see it go to 45 degree.  Active Angle is set to 0° in both cases.  Nothing stands out about the dimension settings.  If I place a new dimension the text orientation is horizontal.  The Change Dimension tool doesn't change the orientation on the copied dimensions.  I can't see anything out of the ordinary on text or dimension settings.  The problem isn't limited to a particular DGN used as the reference.

Screen shots below are before and after copying respectively.

Only fix has been to delete the dimensions and re-dimension.

Thanks for the help.
