Links displayed inconsistently. 6.3.4 and Blanco theme

I’m using RW 6.3.4, Stacks 3.0, and the Blanco theme to create a tenure portfolio. Links are not displaying consistently after publishing. For example, one link with be underlined while others are not. In edit mode they show up fine, of course. I prefer to have visual cues for all hyperlinks in the text body. It’s not possible to make them bold face or colored since the theme default doesn’t allow it. At this point, I don’t want to customized the theme either.

Thanks in advance for any suggestions.
