Unknown devices on lamps with modell id in product name

I found an interesting bug, I couldn’t find ANY info on that. So I bought 10 lamps yesterday and most of them, although working flawlessly are shown as “Unknown”. I suspect that the problem is the productname as you can see in the screenshots.

In fact, out of 8 lamps that I have only are not “unknown” and those have proper product name instead of Modell ID

I’ve got the same problem. All my lamps but one (the first one) are “unknown devices”.

Anybody got a solution?
