Thanks for reaching out.
I have checked the video, but unfortunately unable to recognize the reason behind the problem you are facing. I am not sure if the Classic elements are conflicting with the said plugin, if that is the case, you can use the V2 element and check if that helps. I would suggest you update the Pro to its latest version i.e. 6.1.7 and check if that resolves your problem or not. If not, please provide login credentials for your site in a secure note to examine it further, including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
– Specific page(s) where you are having the issue.
