TCP Listening Port sometime don't display in the"Active Connections" windows

TCP Listening Port sometime don’t long time to display in the"Active Connections" windows, Show time is 0-2 sec Only (CIS4.0.xx.779 win7 x64)

I open my software (after close and reopen it to test)
Sometime is long time to display, but sometime not.

PS: I can’t see any windows system Listening Port (ie.445), maybe is same problem…

Please don’t hide the Listening Port.
