An error occurred: invalid infrared command format

Hi,

first I want to say thank you, for this great integration. I would like to use it for my air conditioning. I have configured two buttons in the switchbot app (only ON and OFF). I also configured these two buttons in HA (ON & OFF). Only the OFF button is working, if I press ON I get this message: An error occurred: invalid infrared command format. Could you help me please?
