Arming whilst exit door is open

Hi, I’ve run into a small but irritating issue. We have the system covering our garage/workshop. With our old alarm it would allow us to arm the system with the main door open (we often leave the door open when using the workshop so its a bit annoying to have to close it to arm the system) and then we could walk out, close and lock the door, no problem. It seems that with this system I have to bypass the door sensor in order to do this, which negates the point of the door sensor if it’s not activated! Please help! Thanks.

The bypass is only temporary to let you know it’s open… once you close the door it is then armed automatically.
