Good call, yes there are! The device is an Inovelli NZW37 - it controls two separate lamps.
When I try to control both of them (the parent), I get these:

When I try to control the left side lamp, I get these:

When I try to control the right side lamp, I get these:

There are no errors on the dashboard UI, I just get the "sending" and the hourglass until I refresh the page.
Side note, I did run zwave repair yesterday, but it didn't seem to do anything.
