Woocommerce add to cart button not showing up on variable pages

Once I updated woocommerce my add to cart button won’t show up on any of my products that have variations.

I have checked for js errors, tried deactivating all the plugins to see if that is what is causing it, but still can’t figure out why it’s not working.
