Zstick 7 and zwave remote (Sunricher) not working

Hi everyone, last week i moved from my Z-Stick 5 to a 7. al works fine and devices being included.

I also have a SR-ZV9001K12-DIM-Z5. This remote worked perfectly with the gen5. However although it is added to the 7 stick, commands being reconized and also being included on the remote itself it doesn’t work. when ever i press a button the associated device e.g. dimmer is not responding.
