How to update font color?

I have gone into the advanced setting to change font in the drop down box and it doesn't change to the same font as the main text. 

As you can see in the screen shot, the assessment questions are black but under Likelihood and Impact the font remains white. 

I have chosen 

Colour Scheme, TExt, Black but only changes main body not the selection text in the drop down box. 

Please help.
