Secondary Button color is not the same across website

Hi,

We have secondary buttons throughout the website and for some unknown reason they are not the same color.  

Website: theimerian.com

Password is:  B^tt3rB^tt

For example, the color of the Learn More button on the Explore page is the color we want.  It is a darker purple.  

If you click on the Spirits page, the buttons there are a lighter color (which appears to be the color of the color pallet) . 

We'd like all buttons (primary and secondary) across the website to be the same darker purple.  How can we fix this?

Thank you in advance for your help.

Thank you.  I was able to update the various button colors throughout the site.
