Vera Home modes, tripped sensor are notified before Home mode is changed to away

Is this normal?
I use a keyboard to change the home mode to away etc. To operate the keyboard, I have to trip a sensor. I’ve set a delay of 30 seconds on the home mode settings page. I’m getting notified, even if the system is not armed yet…is’nt this a bug?
How can I solve this?
best regards,
Olivier
