Ensure all materialized view refreshes are complete prior to upgrade

I got this messge in the log of utlu112i.sql script

WARNING: --> There are materialized view refreshes in progress.
.... Ensure all materialized view refreshes are complete prior to upgrade.

I ran the select statemen

SQL> SELECT DISTINCT(TRUNC(last_refresh))
FROM dba_snapshot_refresh_times;
  2
(TRUNC(LAST_REFRESH)

10-JUN-2005 00:00:00
15-JAN-2013 00:00:00
05-FEB-2013 00:00:00

Here is the result. Should I do something on these 3 mviews?

Thanks
