Image Trace / But creating outlines for text equivalent confusion!

When I create Illustrator coloring book pages in black and white with text quotes over background patterns, I'm having a weird problem. Letters like "O" or "B" with "holes" in them print with wierd white circles that block out the patterns that should show behind them. Sometimes I don't see those white holes onscreen. But I see them in the printouts or in the saved PDF.
While I - kind of- understand the "Ignore White" command in the Image Trace Window, I can't figure out what to do when I CREATE OUTLINES under the Type dropdown. So confused! Many thanks for any help with a solution!
