Fibaro Door Sensor

Hi I have a problem with my door sensor. It works fine apart from the light is constantly flashing. I have read that this is due to not being included correctly but there are no errors in the logs and it updates when opened and closed. Any help would be appreciated.

Remove the sensor and re-add will probably fix the issue

I have removed and reset the device several times with the same outcome. Seems strange how it updates the open close commands correctly but the light stays on. I will keep trying.
