In most cases, this behavior is a result of the Lunar Effect being enabled. The Lunar Effect reduces, never increases, the intensities set in a schedule. The effect scales your intensities based on the current cycle of the moon. This means, that during a new moon (1-2 days every month), your lights will be off for the duration of the Lunar Effect. If this is not what you want, you will likely want to disable the Lunar Effect.
