Default Screen Lock widget does not work on Kitkat 4.4.1

Yesterday, I rooted my Nexus 5 and side loaded 4.4.1 update. Due to root, it reset my phone to factory default. So after I reconfigure my phone, I tried to use Dash Clock widget which use to work before the update but now screen lock does not show up at all. I already enabled widgets in Settings\security.

Any feedback will be appreciated.
