Define Button Theme in Foundry

I have built a site using Foundry and Sitelok. I have used the Form Designer to create my forms and this includes an option to follow the Rapidweaver style to the form. This works for my fonts and input box text colors, but I found that the buttons themselves are colored differently. Every button on every page has the same color combo applied, but stye are not the same as the other buttons I have defined on the rest of the site. I can achieve the button coloring that I want if I uncheck the “follow Rapidwever style” but then I lose the font and spacing and.

I looked at the html code on the site and the class of the button is “button btn”. I am not able to find anywhere in Foundry where I can define a default theme button type. Does anyone have any experience with this or have found workarounds?
