Custom input names aren't shown
Title says all. 

I don't know what broke it... both the iOS (13.1.3) and the macOS (10.14.6 - 18G48f) Home app shows the AppID instead of the custon names I've added to the inputs. It worked previously (like 3 months ago or so) and I don't see why it doesn't work properly now...

The Homebridge's version is 0.4.50, which I've just updated - along with npm.

Here's the config I'm using:
