I inhereited a direct mail INDD file and am seeing a bunch of squiggly lines under random sections of text (see attached image with 4 different squggly line colors). I checked Preferences > Spelling and that's not helping me understand what's going on (screenshot attached). Any clues what these colors are for and/or how I might turn them off? There are a lot of them thoughout the document and it's really distracting to look at (but they do dissapear if I switch to Preview mode). Thanks!
I agree with Laubender. You'll find the Conditional Text panel by choosing Window > Type > Conditional Text. If you see anything other than "Unconditional" in that panel, then follow Laubender's guidance.
