I get some hidden buttons over the price table when embeded into my wix site. Sometimes they show up, sometimes they dont. Also, the featured plan is chopped in the top.
Hello @Juan_Pablo 
Thank you for contacting us!
This image you’ve reported is the information panel. You’re the only person who can see it, and you can only see it when you’re logged in to your Elfsight account. It’s displayed for you as the account owner.
When you log out of the account, you won’t see this panel again, and your website visitors never ever see it at all.
You can check the widget on your website in incognito mode to make sure that no one else can see it.
This being said, here is the special article about it - Why I see a panel above my widget
If any other questions come up, please do not hesitate to contact us. We are always happy to help!
Have a nice day
