Event Blocks - Adding/Removing/Moving Synced Elements

I would like to add and remove and shuffle around some of the synced elements in an event block within a landing page I've created. For some reason, I can only do so to the image and event link (button) that are on the original event page, but all other elements like description, start date, and location are immovable and can't be deleted. Your webpage (https://knowledgebase.constantcontact.com/email-digital-marketing/articles/KnowledgeBase/51048-Add-an-Event-block-to-an-email?lang=en_US) suggests that I should be able to move/manipulate all elements (I know they can't actually be edited). If I hover over or try to change any of the elements I listed, the upper editing banner just says "Event" next to the trashcan, as opposed to "Image" or "Event Link" with options to adapt or delete those. Any advice?
