Certain activated fonts (Monotype KK) do not appear in the character menu

I added typefaces Mode Mincho A Large Std and Mode Mincho B Large Std from Monotype KK (formerly Fontworks Inc.) into Adobe Fonts. When looking in the character menu in Illustrator, neither fonts appeared. De-activating and re-activating the fonts did not work, nor did restarting Illustrator. This is in a release version of illustrator.
