Lights won't turn off on schedule

I just picked up a smartthings hub and a leviton DZ15S-1BZ Decora Smart Switch

I can turn it on and off from the app 100% of the time. I created a schedule to turn it on and off a few hours later. It always turns on automaticity but never turns off. I have tried doing it in the same light automation as well as separate “smart lighting” on and off tasks

Any ideas? I can’t see it being reception / range as it works from the app when manually toggling it
