ceiling LED light sunset scene issue

Dear all,
when I select sunset scene in mobile app for my Yeelight Ceiling LED light, it gradually diimms for 15 minutes as supposed to but afterwards it automatically goes back to original intensity in a second. This makes no sense, I thought it should turn off completly. I have not found any topic regarding this issue, light reset did not help. Has it been reported? Is there a fix?
Thank you!

Could you have a try again? We have fixed the issue, the lamp will turn off automatically after 15mins.

It works well now. Thanks!
