Hi @Peter_Bittner, I completely missed your previous post, sorry.
In fact, the check for open motion and contact sensors is one and the same so there should be no difference there.
Could you disable the Only when a Surveillance mode is active setting and do some testing: Have motion sensors active and doors/windows open when changing the Surveillance Mode.
After that, have a look in the log on the Dashboard and post a screenshot here.
(On a computer at the developer pages after using the css fix.)
