Pairing Bulbs with CC2530 Router

Hi,

I have paired 3 x GU10 IKEA LED1537R6 with a 2530 Router.
Also created a group and added the 3 bulbs to the group.
The configuration.yaml looks okay.

However when I try to change the state from ON to OFF of either the group (Keuken_Spots) or one of the bulbs (Keuken_Spot1), nothing happens.
When I look in the log, the OFF command is send to the router, but it never gets to the group or bulb.

Here is the log:
