Light color / temperature buttons not immediately changing light mode

Hi, the light mode selector UI is not behaving as it should. Previously, when I press any of those two buttons inside the light blue box (see image), the light mode immediately changes, meaning the bulb would turn to the last selected color or turn to white with the previous light temperature (depending on the pressed button). Now, this is only effective when I select a color or a light temperature using the available selectors, which is very annoying since it will apply the change with whatever value is selected after pressing somewhere on the screen.

Any idea why this has changed recently?
