Hello,
1. Please check now. I’ve uploaded an image – http://prntscr.com/jaqqql
2. 1) Please explain the desired result.
2) We have 3 types of buttons on our site – light (for example http://prntscr.com/hdcwhy), dark (for example http://prntscr.com/hdcwxi), active (for example http://prntscr.com/hdcx3r).
Button text color can be changed in Theme Options > Styling -> Content > Customize buttons.
In your case, set Button text color in Active buttons options.
Regards
