I just published a wizzle, a review of the children's book Tumble Tower. There are four text boxes, and three have the grey background. The first two text boxes, which contain the actual review of the book, have the grey background BUT each line of text has its own white background. The third text box with the grey background is just gray, no white lines.
Is this just appearing on my monitor, or is it an actual glitch on the page and if so, how can I get rid of the white boxes around the text?
