Can you provide a sample login username and password? The issues appear to only exist when the user is logged in, as I don’t see a calendar or a logout button.
Based on what I can see, you have some hidden or invisible elements covering up parts of your page. You’ll need to find those in the editor and remove them, that should fix it.
Yes, you are right. There was hidden floating group created by mistake in one of the reusable elements. Removing it fixed the problem. Since it is in reusable element, same problem was showing up in multiple pages. Thanks for the help.
