I’d guess you shortcutted to moon from off? That doesn’t reset the saved level to moonlight. You have to set it to moonlight by actually adjusting it to moonlight, not by the hold from off shortcut (that doesn’t reset the memorized level).

If you’re not sure what level the light has memorized and you need moon just hold the button till it comes on and ramps up one step then release and hold again so it ramps back down that one step, this will memorize moon.

A FW update would solve it too but that’s a lot of work if you’re not already setup for it!
