not adding to cart when integrated with Formidable

Hi there, this plugin is great. I just have a question. I have formidable forms integrated into woocommerce product page, but when I click add to cart the sidecart opens but says cart is empty. if I click add to cart again while side cart is open it will then add the product to the cart.

If I have ajax disabled then it will add straight away with a page refresh. I’m guessing it’s something to do with this additional plugin, but is there a way around this issue? thanks for your time.
