It looks like the current firmware on the IQ Panel is 4.4.1. Can you try updating to the latest 4.6.1 firmware?
Can you also try turning off the switch by pulling the tab on the bottom for about 30 seconds. Then set the panel to exclusion and try again and press the top paddle one time. If it fails, try pressing the bottom paddle one time.
If nothing happens, try setting the panel to inclusion and try again.
Is this the only device you are having issues with? Were you able to learn in another device of the same model?
