Smart Lighting sporadic

Hi all, I wonder if anyone has any idea about what could be going wrong here.

I had a Fibaro Dimmer 2 and a Fibaro Motion sensor in Smartthings and using Smart Lighting a simple set up. If there is motion and lux <= 60 then turn the light on for 2 minutes. Simple and it worked for the most part. the lux reporting was not great with the Fibaro motion sensor. I changed it for a Hue motion sensor because their lux reporting seems to be second to none. Since that change though the light comes on but doesn’t always turn off despite there being no movement.

Any ideas?

Thanks in advance.
