I know this is an old thread, but any chance you found a solution? I've noticed the same thing.
Also, have you found a good way to have 3 automatic settings? I'd like high light, low light, and completely off, but the built-in functionality supports just 2 automatic settings.
Finally, have you noticed that a power outage "confuses" the lights? The settings and time are remembered, but the lights stop adjusting as programmed so you have to hit resume.
