I edited the theme so the template.js file is now loaded as version 1.0.1 this will bust the server cache and now the double category select is gone:

In regards to the search… I didn’t do anything, not even visit the Template Customizer for cMap, the search is gone.
But I wanted to see if I could duplicate the issue so I went to the Template Customizer and turned it back on. The preview worked, but the page did not update, just like you were experiencing. But I know the reason now…
You are using SiteGround (I do too, great host) you have the Memcached option enabled. This caches frequent db queries. The WP options is a frequent db query and apparently the Memcached cache is not purged when Customizer options are saved. Nothing I can do about that since that is a core WP API. I’m “simply” using it to enable the Template Customizer Feature… like theme and other plugins can.
Any way, after saving changes in the Customizer, go to the admin SuperCacher page and turn off then then back on Memcached. That’ll purge the db query cached and your Customizer changes will be reflected on the site.
Hope that helps!
PS. The server cache… I had that same problem where updated CSS and JS file were not being served. I fixed it by changing something in the cPanel SuperCacher options page. I forget what I did exactly… I think it was flushing the master static cache or maybe toggling it off/on.
