Problem with BitComet and Comdo when changing the Stealth Ports Wizard

I have a problem with BitComet and Comdo when changing the Stealth Ports Wizard.

Conditions of the the test:

- XP with the last actualization;

- My computer connects to a router.
I configure the port 5000, for my computer;
- Configuration of the Comodo Internet Security, last version with the last actualization:
Firewall set to, Custom Policy Mode.
Stealth Ports Wizard, set to, Define a new...
I choose the network zone detect by the program.

Information of the tests:

When I execute the BitComet, the Comodo detect that the program attempt access to port 5000.
I accept.

The BitCome works fine, port 5000 is open for communications;

Next, i use Stealth Ports Wizard, set to, Block all incoming...
The BitComet can not communicate with port 5000, as expected.

I use the option, Stealth Ports Wizard, set to, Define a new...
I expected that the port 5000 is open for BitComet, but, the Comodo blocks both UDP and TCP, for inbound connections to the port 5000.
Only after I use the option, Stealth Ports Wizard, set to, Alert me..., the Bit Comet works fine.

I set again, the option, Stealth Ports Wizard, set to, Define a new..., and choose the same network.
The Bit Comet works fine.

Thank you
