Color temp of Ikea Floalt not updating in HA any longer

I have successfully been able to control my Ikea lamp (Floalt) from both the Trådfri remote and from HA following the suggestions in this thread. Now an issue has however occurred. I can still control the color temperature from both remote and HA but the when changing the color temperature using the remote it does not reflect in HA. On/off and dim up/down still working as expected. Anyone else experiencing the same and/or has a suggestion for resolving this?

This seems to be working again after a re-configuration of the Trådfri five-button controller.
