Avada child theme issue

We have a child these for Avada and have updated it. When trying to add attributes to a product variation in WooCommerce, the dropdown is not available because it is blanked out. You can not add new attributes at all. We enabled troubleshooting mode in site help. All we enabled in woocommerce and when selecting the main Avada these, everything works fine. When selecting the child these, it no longer works. So, we have determined it has nothing to do with any plugins. The theme shows it is up to date. This just happened in the last update of WooCommerce. Has anyone seen this and does anyone have a solution?
