Smartthings button only turning off?

Hello, I have been using a couple of smartthings buttons with lifx bulbs fine for the past 6 months.

I have just installed a tp-link mesh network and now my buttons are playing up. They will only switch lights off or to the desired brightness if the light is already on. They will not turn the bulb back on if it is off.
I have toggle on and I have tried resetting.
Please help, I don’t know what to do.

Thanks, M

Oh, and my smartthings sensor is doing the same thing for another bulb, it will switch the light off if the door is closed, but it won’t turn the light back on if the door is opened.

Help.

Is it possible this caused interference in the 2.4Ghz band? Maybe try switching the frequency on your mesh. If that doesn’t do it, try moving a button to a different part of the house for testing. Lastly, new batteries?

Thanks, don’t think I can have mesh on one frequency. Just a bit weird buttons work OK as long as lights are on, but if they are off won’t turn them on. Same for sensor. 3 things behaving exactly the same. Batteries and house position not a problem
