It sounds like you're encountering a common issue where a site plan isn't visible as expected. One potential cause is that the site plan might be positioned below the "-------- Ground -------" tag in the site plan list order. This placement is intentional and part of the system's design. When a site plan is at the bottom of the stack like this, it will only appear on the 'surround'.
We typically recommend placing elements like satellite imagery at the bottom temporarily, so they don’t clutter the primary view. Try rearranging your site plans so that important ones are above the "Ground" tag, and see if that resolves the issue.
Another trick you can do in this scenario is to 'pop-out' the window, this will switch the site plans into their own window without the topography. This can make it much easier to align site plans together :
