Dont worry about the dashboard yet, devices need to function from the device page before you worry about anything else.
I would shut the hub down and pull power for 30 seconds to reboot the radio.
If you are running platform 2.4.2 you may also need to go to zwave details and then click the "switch to legacy gateway" button. The new gateway Zwave JS IMO was a total mess on 2.4.2. You can always switch back to it once they work out more bugs.
The two that paired as "Device" probably did not fully pair, you can leave them enabled in SmartStart, and then exclude them. They should immediately try to re-join.
