First of all, are you using a hub? If you are, which one. It sounds like you are trying to do the settings via the switch buttons, which is more difficult than using a hub.
If you put the switch into the Smart Bulb Mode inadvertently, then that explains why you can’t work the switch at the paddle, because that is exactly what that mode is supposed to do. I don’t think you want that.
Start by factory resetting the switch. Press and hold the config button and then while holding the config press and hold the up paddle. Wait for the LED to turn to red, then release config, then the paddle. You’ll see the switch cycle through colors and start pulsing blue. That will get you back to factory fresh and the paddle will work to operate the lights.
Post back about the hub and we’ll go from there.
