Newly Installed "Ink" Theme Keeps Refreshing in WordPress "Customize" Page

I recently purchased and installed the “Ink” theme to my WordPress site. When I go to the “Customize” page it constantly reloads preventing me from using the theme. I have already de-activated all the plug-ins and it doesn’t help. If I switch to a different theme the problem goes away. What can I do to stop this from happening with the “Ink” theme?
