Actually the port should not remain "Open" because the software should
close it when done, by that I mean it should cease "Listening", and a
listening port is harmless anyway unless the software doing the
listening is flawed, rather like you listening for the phone but only
answering calls from numbers you recognize on the caller ID.

I suspect the message you are getting is trying to tell you that the
port will not be automatically firewalled again until you change it back
manually, this is way different than it being "Open" all it means is
that the firewall will not warn you if that software or something
malicious using the same port tries again to communicate, and that the
firewall will not automatically block this.
