Problem with Lost Mode

After i set the phone into lost mode, i cannt turn off the mode... Where is the option to turn this off again?
I thought after entering the password, the phone would not ask for the password again, but it does every time the screen shuts off. Gerr.

You can clear the "Lost Mode" by:

Go to "Settings" of your device> "Security">"Screen lock"> enter the unlock code of Lost Mode> "Next"> and choose "None"

Can this be done automatically by airdroid after entering the correct password ?
