Hello @CathyS811 ,
Thank you very much for providing the video of the issue as it's occurring. I'm afraid I'm not able to recreate the issue when working in either the 3ge or CPE, though I have seen it sporadically occur with some browser extensions that can interfere with the website's functionalities. Are you seeing the error occur in other browsers, or when you disable plugins / extensions in your Safari? Is the issue also occurring in that one template or in others as well for your account?
