Status of a shutter is not correct

Hello, I use various roller shutter actuators from Homematic and one of them displays a different icon when it is opened. I have already measured and entered the travel time. I don’t see any difference anywhere as to why the status in the kitchen is displayed differently. What do the different icons actually mean? When the shutters are closed the icon is white. Actually it looks like only the kitchen is displayed correctly. All roller shutters are open.
