What cause UDP Multicast Stream Statistics to double count streams

I have a multicast capture of "mpeg ts" packets. When I opend Statistics->UDP Multicast streams I notice duplication of streams in the table output instead of only unique streams. In fact known some unique streams i can see in the capture are not showing up there. E.g I see the same src IP, src prt and dst IP,dst prt pair duplicated. What is the cause of this and is there a fix. Wireshark versions tested: 2.6.2
