Strange rule firing

I have StrongDC(a peer program)
and I have а rule for restricting the program in
LAN
50.200.100.0 / 50.200.200.255
100.200. 0 .0 / 100.200.200.255
200.200. 0 .0 / 200.200.255.255

And I noticed (a long time ago) after some installations of Windows (and StrongDC)
when I start StrongDC Comodo blocks it’s connections
but if I open Network Security Policy window and close it by clicking (without modifying)
and after starting again StrongDC everything is OK

After yesterday’s reinstalling (windows+programs) I have faced this behaviour again
