I notice that Switch1 isn't learing any routes from Router1 or Router2.
Can you ensure that the adjacencies are up?
This may make it work for you, but you're correct, this doesn't explain why
you're seeing a /16 on the 149, but not on the 139...

Subject: EIGRP auto-summary question
Hey, Group. Why won't EIGRP install a summary for 139.10.0.0 like it did
149.10.0.0????? This has me stumped. >:-|
Here's my logical topology:
