It's not bad, it just means that you are playing a game we don't have in our 'DumaOS Classified Games' list. You can manually change this by adding the ports to the table. Follow these steps:
Click ‘Add Device’ and select your device from the Traffic Prioritization Selector.
Then, click ‘Next’, and select ‘Advanced’ at the top.
On this page you can add individual ports (or ranges of ports) to Traffic Prioritization.
If you wish to add just one port, type its number into both the Start and End boxes beneath ‘Destination Port’. For a range of ports, type the first number of the range in Start and the last number of the range in End beneath ‘Destination Port’.
After this, select your protocol and click ‘Done’.
