Thank you for contacting us. In our tests the “Call to Action” on the Diced theme is working correctly.
We are happy to help you troubleshoot further, but will need some additional information. Does it disappear randomly, or when working on the site? For example, does it happen after making changes to a page?
Can you provide a link to the site for us to test?
Have tried disabling any additional 3rd party plugins you may be using?
