Hi There,
I can see that you are set to have a transparent, square and regular type of button and it doesn’t reflect on the frontend. From your setup I can confirm you don’t have a caching plugin or any caching that might result to this issue. The only unusual I found is the location of the theme. See this: https://screencast-o-matic.com/watch/cbjr6xlLkA. It seems that on wp-content/themes folder you have the pro theme. Inside that folder, you have another pro theme. Try deleting current Pro theme. Using FTP, go to this folder wp-content/themes. Delete pro folder from there. Then install it again.
