Open UPnP ports block does not work

I had some BigIP downloader upnp malware on my network downloaded from vendor (not steam) which apparently known for this in their installer. I have supposedly 5 upnp open ports Udp 6881 / 9308 /9305 when in the app and the block option does not work. I have upnp turned off at the router and resolved the issue on the affected device but firewalla still shows these as open and the block option does nothing.
