A new problem gns3 + stub router + summarization

I'm practice stub and summarization in eigrp and I made this :

R1 is the stub router and all routers have the network statements
I also summarize the route on R2 and R3
the problem is that the summarization is not propagate through the stub router I did used the command eigrp stub summary although it's enabled by default and it didn't worked so I also tried propagate the summaries by the stub router on int fa0/0 and fa0/1 and it's still no working any suggestions???

I'm trying to locate the router image you used, so I can view the config.

Anyway you can copy and paste your configurations on all routers to notepad and post here?

You need to summarize the routes that you're receiving further, on R1 you're receiving a /13 and /14 and you've configured your summary routes with the same prefix length, reduce the /13 to a /12 or /14 to /13 or lower.
