|I have eleven sites which may be the same as you describe.|
They are all included and all have excellent placement but the only thing which shows up in the listing is the URL.
There will be nine normal listings on the SERP and then somewhere in the results will be one of my sites which just says
with no description or title. Is that what your site is showing?
In all cases, these sites are on hold waiting for their content databases to be completed. In the meantime, they are parked, re-directed and masked. Those are the only sites of mine which show up that way.
It appears that google is reading the masking as the final page and stopping there.
