"Main Street" seems to display just fine.  I'm not sure what object you were trying to tag as "Downtown Area", but using that as a name sounds counter to OSM good practices.

Note that the OSM website can take a couple days to show new content and there are some types of content that just aren't rendered on the website at all, but are used by other renderers.
