Zooz Zen30 and pairing tomfooleries along with lasting issues

I purchased two Zooz Zen30 double switches off of Ebay and had one hell of a time getting them included into my setup. Probably a dozen or so exclude/include cycles until everything was running as you would expect it to. I have a lot of Z-wave devices, and these are the first ones to give me trouble.

Now to a lasting issue, which is more of a nuisance than anything else. When HA restarts, everything comes back online EXCEPT the two Zen30s, which are grayed out on the dashboard. The moment I physically press a button on the switch, Z-wave JS finds them right away and functionality works as expected until the next restart. Has anyone ever heard of such a problem?
