I ran an audit on all my drawings that are referencing that data shortcut folder and there were no errors. I also do not see any yellow error warnings in the prospector. I'm not sure why all of a sudden this popped up after I simply labeled a contour. If it isn't one problem, there comes another.
Is the text height set to zero in the "text style" used in the "text component editor" format tab of the contour label style in use (source file) that wont display when xrefd to other file? Verify the "text style" default height is set to zero in each file on the text style dialog.
