Enfold Theme & FormCraft3 not working properly!

Hi,
the Enfold Theme seems to be colliding with the FormCraft3 Plugin I’m using for my new project… The theme imposing their own CSS over the form elements (Sreenshot Chrome). The CSS is messed up badly in Firefox as well (Screenshot_Firefox). I contacted the FormCraft support first but they told me that it is a theme related issue, I also tried commenting out the form section in the base.css file but it didn’t work out. I’d love to get any help for my problem.
