Fonts selected when creating CSS are not visible in font drop-down menu in design view
My company uses RoboHelp HTML version 9. We are going through a rebranding effort and are now trying to change our Help system to match the company's new fonts and colors. I created a new CSS to match the company's style, but fonts that I selected when setting up the CSS

do not appear in the font drop-down menu in the Design view.

Does anyone have any ideas as to why this would occur and what I could do about it?
Any and all suggestions are appreciated.
