Customizer stuck on Loading

Hey Team - I have been having issues with section in the customizer not loading. The testimonials, team, and featured content section is stuck on loading and only shows the option on the left bar of where you want this section to be displayed. I choose home page and entire site but still do not have any other editing options. This happens on other sections as well. Is there an issue with the theme? I opened up a support ticket saying I could not download 2.2, maybe that is why? Thanks for the help. My site is Niceguymikemusic.com
