IKEA remote does not change colour correctly with deconz

I use a conbee II stick to controle my IKEA Tradfri components. If use the home assistant UI everything works fine, but I still want to use the IKEA Tradfri 5-button remote control to control light groups. On/off button work, dimming up down in steps works, but when I use the arrow buttons to change the colour temperatre I am only able to set afdter pressing for a long time either the warmest or the coldest temperature. The colour temperatyre change does not stop or cannot be set in steps, but if I press one of the button the colour temperature changes gradually within a few seconds to one of the extremens depending on whether I press the < or > button. That seems to be a flaw in the PhosCon UI. Any idea on how to solve it?

Just noticed the same - did you figure out what was wrong?

Same problem here.

same here, and i tried to hold the on/off for 5 sec and then release and double press either the left or right key. its supposed to change the mode of the remote
