I figured out where the issue is, but not the solution. I have vision issues, so in all of the handouts I read, I select all and change them to Heading 3, unbold, and as I read I add formatting to the text. This makes the font larger and easier for me to read (the default size is way too small for me). After I change the text to H3, it removes the ability to use italics. When I click the italics button, it depresses, but no result is shown on the text. This is happening in every module I have now. I tried changing to H3 and then removing formatting with the button. It rebolds but does not fix the issue. Italics works in the original text size. It isn't until after I make changes that the issue occurs. I tried in dark and bright screens. I also color code my text, which helps me deal with the issue visually. (like a certain color for dialog).
