Hello @SWCmarketing,
Sorry for your inconvenience, I checked your website it seems that your website URL is not updated properly from HTTP to HTTPS. When I try to access your website dashboard the WP-ADMIN URL turn into HTTPS.
You Revolution slider’s fonts are loading from HTTPS URL and your given page URL is with HTTP because of that the Revolution slider’s fonts are not loading so slider pagination arrow is not displaying there.
Screenshot with HTTP URL
If you check your page by HTTPS URL https://www.southwesterncoaching.com/student-coaching then you can see there is no issue with slider pagination arrow. It is working fine.

I would suggest you replace the URL properly and check this again, there are many URL replacement Plugins available in WordPress which help you to replace the URL.
This article will be helpful in this:https://www.wpbeginner.com/plugins/how-to-update-urls-when-moving-your-wordpress-site/
Also, remember that the exact URL should be mentioned in Setting > General , WordPress Address and Site URL , including the protocol i.e HTTP/HTTPS.
Thanks
