Smart Lighting App freezes

I want to add a new smart light app with a on and off at a specific time.
But when i try to enter the time for the app to turn on or off instead of the time being listed it just shows a line and then stops responding. In the old smart things app i had several smart lighting apps that worked well.
Any suggestions?

I saw this on my iPhone. I then opened the app on my iPad and the time entry behaved correctly there.
