Add to Cart button has to have the page refreshed between every option

[Khancock86]

Hello. I am using the Dawn theme. Everything was working well until yesterday. I used the app- King Product Options. I added color options to my listings. It looks and works well except that the add to cart button is grayed out unless I refresh the page. My customers will not know to do this. Everytime you change an option it grays the add to cart button back out until you refresh again. 

I reached out to them and no help.
