Underlined/highlighted text not staying formatted??

I've chatted with support but am hoping someone can maybe answer this before they email me back.

I'm having issues with some highlighted/underlined text not staying formatted. I've tried everything possible, it's showing that it is formatted on the edit screen, but no matter what browser I use, cleared cache, restarted computer, etc I cannot get the formatting to show up when I view the website.

I want it to look like the first photo, but it keeps going to the second (in another area on the same page as well). The third image is just showing how it is saying it's formatted.

Can someone go HERE and let me know if the "F" "A" "C" "E" in the middle section and the FACE in the bottom contact section are highlighted? 

First section:yes, second section: no and yes (it is highlighted the same colour as the background).

Ugh, thank you for letting me know! That's the frustrating part, the first section worked so well I don't understand why the other 2 aren't lol
