Auto Lock Schedule not working :(

Have a Smart Lock Touch.
I used to use auto lock, but one of my kids in and out all day and it drained the batteries quickly.

I turned off auto-lock and have it set to schedule auto lock between 8:30pm and 10am.

it worked fine for about a month or two. The past few weeks we have notices the door is auto locking during the day (auto lock is OFF), and NOT auto locking at night, as it should.

I double checked to make sure I hadn’t accidentally changed the time from am/pm. Nope. everything is set the way it should be.
What gives??
