Could you please check how it works with some default WordPress themes like TwentyTwenty or WooCommerce Storefront to understand is it our theme issue or not?
With the latest update, Woodmart Version: 6.0.4, the issue seems to be resolved for Single Products and Variable Products, BUT It IS NOT RESOLVED FOR Bundled Products.
Please update so we can fix this issue for good.
Thank you!
Try to disable our AJAX add to cart option in Theme Settings -> Product page since it is not compatible with third-party plugins that add new product types. It works only with WooCommerce standard product types.
