Why are my dynamic text fields not populating?

For some reason my dynamic text fields aren't populating anymore. The only new thing I added before it stopped working correctly was a new button, but either way..if I take the button out or not, no text field is populating. This is on all the layers I have. If I change the font of the text fields, they start populating correctly..and when I make all of them the same font..they start not populating anymore!
