Can you show us a screen capture of part of this poster that shows the problem?
You said you were making the text bolod by applying a stroke. Were you using a style, or locally selecting words and applying the stroke?
Thank you for the quick response. I restarted my computer and the program and tried to export again and it seems to have fixed the problem. I am not sure what could have caused it in the first place.
That could happen if you chose to "redefine paragraph style" without
noticing that your text cursor was in the middle of one of the bold
words in the paragraph. But this is a guess based on the minimal
information you've provided.
If that were the case, you would need to redefine the paragraph style
not to use bold. If you've used a character style for your bold words,
they will stay bold.
