Just one more note while I'm thinking about it... Let's assume there's more
than one router injecting those networks into the area. Your distance
command would need to reflect the router-id of the one who was WINNING the
OSPF RIB election and being handed to the routing table.
If you were picking the losing one, you'd not see any difference until the
other router was shut off/removed.

Please use command "sh ip ospf database" to see the router-id of the real
advertising router for these routes.
Speaking of your configuration, your router is in area 1, and routes
"139.3.6.0 and 139.3.7.0" are interarea routes. In other words, the real
router advertising these two routes are ABR of area 1, instead of original
router which inject these two routes into ospf domain.
So puting the router-id of area 1 into the command surely will work.
