Port forward error on The HubOne

[#1]

Conflict The game or application you’ve selected conflicts with an application () you’ve already assigned to another device. Please remove the other application or select the same device.

Just getting this message when I try to add more that 3 ports to one device. Then even if I delete one to add another I get this message. Going to try a hard reset (what I found in an old BT thread about the HH) Any ideas or is it the router? Do I need to get it replaced? Thanks Tom

Just an idea. Have you tried just creating one Game/Application and assign all 3 port forward rules to it?

The Hub One is a rebadged Home Hub 5 Type A
