we have installed toolset at our page. We are using hestia pro theme and some other plugins as well. Since the toolset is installed we could not change the sections at the customizer - have a look at the screenshot
Thanks for the theme, I've tested it with our Views and Types plugin active and the customization pane still remain normal and I wasn't seeing any issue with it.
Could you disable all the non-toolset plugins and keeping our plugins enabled and let me know if the issue still remains.
have done the test: deactivate all other plugins and only the toolset plugins are active: same result - customizer not showing all sections.
As I described earlier: FYI - I have done some testing with all other plugins deactivated and toolset plugins activated: if we active TOOLSET views plugin - the customizer of the HESTIA PRO theme will not proper work.
Have a look at the screenshot - could be the settings. But it will change nothing - if we change the settings for the views.
