Noob: Missing z-wave devices

I apologize if this has been discussed already.

I have an existing z-wave network. Everything works perfectly, I was just too frustrated with the Amazon Echo integration so I decided to add a ST hub. I was able to add the hub and most of my devices appeared in Things. However, there are three GE Dimmer Paddle Switch (Z-Wave) devices that weren’t found (it did find 2 of them).

I went into Home/Hubs/Z-Wave Utilities and ran the Repair Z-Wave Network. In the Repair Messages, it shows all the devices but says Failed to update mesh info.

Any ideas?

Power off the switches using the air gap or fliping the breaker for 15min. Just like your PC a reboot can fix zwave/zigbee weirdness too.
