Sleep watchface is displayed with the start of sleep schedule and in the morning it automatically returns back to normal watchface when the sleep schedule ends as expected.
Yesterday, before my sleep schedule started, I enabled battery saver setting during sleep which is supposed to turn off some features to save battery. Battery saver mode is enabled by default when my sleep schedule started, again as expected. In the morning when my sleep schedule ended, battery saver mode is disabled automatically, again as expected. The problem is that the watchface did not change from sleep watchface to regular watchface. I had to go to controls and enable the battery saver first then disabled it again to see my regular watch face.
I realized this is not related to sleep schedule. When I manually enable sleep mode via controls menu, battery saver is enabled automatically as expected. Then, I disable the sleep mode manually and the battery saver mode is disabled automatically as expected but again the sleep watchface stayed on.
To sum up, if battery saver mode is enabled during sleep mode, turning off sleep mode either manually or automatically doesn't let the watch go back to its regular watchface. It stays in the sleep watchface unless you manually enable and disable battery saver mode.
Here is the video of the problem that I captured;
