Hi David,
Thanks for writing in! Please follow Slider Recolution documentation here (https://www.themepunch.com/revslider-se-doc/layer-actions-links/) and make sure to setup your links accordingly.
If you’re still having issues, then you need to disable your 3rd party plugins except Cornerstone, Slider Revolution and test your issue further. If the issue is resolved, then you can activate your plugins one by one to see which plugin causing the issue.
If you have added any custom JavaScript to your site, you can temporarily remove them and test your issue further.
Also if you have a child theme, you can disable it and see if your child theme customizations are causing this issue.
Please make sure to clear full cache when testing your site by following this guide (https://www.wpbeginner.com/beginners-guide/how-to-clear-your-cache-in-wordpress/).
If you’re still having issues, provide us with an example page URL along your WordPress credentials in a secure note to check your issue further.
Thanks!
