Problem with button color

Hi!

I have some problems with the color of the buttons. All buttons that include the primary color is “in front” of the white text which results in an unintended pink color (see an example on http://smakaglas.se/produkt/whisky/ ).

What could possible be the problem? I have tried other colors without any progress.

Grateful for help!
Tim
