Materialized view 'using' clause

Oracle RDBMS 11.1.0.7

I'm migrating from 11.1.0.7 up to 12.1.0.2 and one of my small schemas has 2 MVs.  When I look at DBA_MVIEWS and the master_link column, I see a db link in there to an old database and a db link that no longer exists.  I can't figure out where that is coming from.  Weirder yet, the MV is valid and refreshes.

I did an impdp and wrote to a sqlfile.  The next weird thing is that I see a 'using' clause with this db link and also an old, nonexistent schema.  The bold references below are the things that don't exist. 

Howdy, Stranger!
