odd icons in new emailss

[cg2437]

Yesterday I clicked on something and now I have these icons in the main body that I have no idea how to remove. I was hoping rebooting would help but nope. Any help on how to remove them?

Here you go Turn formatting marks on or off (microsoft.com)

Thank you. I didn't even know what to look for or how I turned them on.
