Can't find commander pro in system

[camattelaer]

Hi
I have a system with a lot of BeQuiet silent wings pro fans. Due to their amperage, i have 2 commander pro's in my system. When starting cfancontrol gui it identifies the commander pros:

[INFO    ] __main__             | Starting Commander² version 1.2.0 with configuration: {'interval': 10.0, 'auto_start': False, 'profile_file': None, 'log_level': 20, 'theme': 'system', 'mode': 'gui'}

As a results there is no commander pro selectable in the gui. Could you please provide help on how to fix this?

Kind regards and thanks in advance
