Hello,
Canvas is not readily compatible with WordPress or WooCommerce and since you are Customizing the Codes to make it work with WordPress, it is your responsibility to make sure the Custom Plugins works with the JS Codes provided with Canvas.
Additionally, this issue appears to be with incorrect Enqueueing of JS Files and Integrations. Please check your Browser's Developer Console to find out if there are any JS Conflicts. Let us know what you see and we can provide you with further assistance and if this can be fixed easily, but Support on this will be very limited, as currently, we do not provide Customization related Support according to the Item Support Policy: https://themeforest.net/page/item_support_policy .
Let us know if we can help you with anything else or if you find any further issues.
