Hello,
We are responsible for the plugins which are attached to the theme in the part of their compatibility. If a plugin is not listed as a compatible, our support does not cover fixing incompatibility. Sometimes, if it is easy and quickly we can provide a solution.
In this case, all the features are available in Woocommerce or our theme. Here is the demo: https://woodmart.xtemos.com/shop/
And the plugins you are trying to use just duplicate the functionality and conflicting. Please contact the plugin support and ask them to fix the incompatibility. If you still want to use them.
If you need help in the settings, let me know what kind of you need I will help.
Best Regards
