This is the same with all connected lights i am finding. My Hue bulbs do the same thing in SmartThings. i mentioned this to support for the issue I had with my Cree bulbs,
Here is my statement to them:

Yep, when I turn it off and then back on.
When it’s off at the switch, but the bulbs were on prior, smart things still shows them as on. When you change the state manually in smart things to reflect that they are off, and then turn the switch back on, the bulbs light up, but they still show as being off in smart things. It’s like the hub doesn’t know what state they are in any more as it’s waiting for an action to trigger the polling of the state from the bulbs.
and this is their response:
Thanks for the info – that first part is expected for now, as the state is essentially “unknown” when the bulb is turned off from the switch. But the second part seems like it should work better than that. I’ll pass that along to our QA team to take a look.
Thanks again, and let me know if you have any other questions.
