Cannot display appointments that are available

I have Appointment Plus shortcodes in I originally included some instructional text within the app_services shortcode, that I later decided was better place before any of the shortcodes. The trouble is the text within the shortcode refuses to disappear in the visitor view of the site. I have cleared cache from WordPress as well as from Appointments Plus. I have also cleared cache from within all the three browsers I am testing the site on. But even 4 hours later, the text that I deleted from within the app_services shortcode still appears on the front-end of the site on all three browsers
