Add light to group: "Failed to disable reporting for 'LIGHTXX' cluster 'genOnOff'

I have a group that is working with a Hue dimmer and a Hue light and then I would like to do exactly the same, but in another room. This time I get an error after I have added the light to the group stating:
" Failed to disable reporting for ‘Hue_being_loft_3/11’ cluster ‘genOnOff’"

I have a third room with same setup that also fails.

Any ideas?
