List bar menu close but does not open again

Hi All, perhaps it’s an old bug and is it solved already. (We’re still on the 2018 version, hopefully we will update this summer)  Is anyone know with the behaviour that a list bar menu group is opened when starting the application. In this group is only one item. If we close the group, the group will not open again. It stays closed until we restart the application, and then it’s opened by default. I don’t see any settings in the SF or the IAM related to this ‘feature’
