There is a problem that you have many paths for router from BGP
to collector table:

Standard: RO_149 -> T65050 -> C65050 -> Collector
Unexpected: RO_149 -> T65050 -> master -> Txxxxx -> Cxxxx -> Collector

You should add import filter for Cxxxx to allow only routes received
from associated BGP connection and not the routes received through
master table.
