Well I don't think that's the problem because below you have a similar
scenario, where both summaries are advertised. The second one does not
suppress the first on this case.

area 0 range 10.150.190.0 255.255.254.0
area 0 range 10.150.128.0 255.255.192.0 cost 1000

Hi Roberto,

Line 2 is summarizing networks 10.150.0.0 - 10.150.127.255. That
includes network 10.150.12.168/31.

My best shot at it would be that the more specific summary gets
suppressed due to the existence of the 10.150.0.0/17 summary.
