I think you're not using quite the right terms. When you say "building" the calendar system uses the word "location" and where you use "location" the system uses "rooms & equipment". So what you mean to say is:

If I add a new location (same name), I get the defaults - but I can't delete the existing location (that's probably good).
As RussellHltn said, you need to make sure you have the "This location is a meetinghouse" checkbox checked. But if these are locations that were added automatically (came from the FMAT database), you won't have such a checkbox; there will be text that says "This location is a meetinghouse" but you'll have no way to check it or uncheck it.
When you are editing the location, do you have a Remove button at the bottom, to the right of the Save button and Cancel link? If so, it's a location that was added manually. But if you don't have a Remove button, and you also don't have a checkbox by "This location is a meetinghouse", then this is odd indeed. You would need help from a developer to fix the database.
