We updated the theme recently, the problem is recently we found many components/items of WPBackery not working properly and has some of their options disabled.
Please refer to the picture attached, it is one example of the section title item.
I have logged into your website. It seems that you are using the old version of WoodMart core and the Wp-Bakery page builder plugins.
Please update the plugins to the latest versions then clear the cache and check back. If the problem continues then deactivate all the third-party plugins and tell me with the permission to debug then we will troubleshoot with the theme plugins.
