HomeKit: ["WindowCovering"] works, but {homekit="WindowCovering"} doesn't?

The title says it all (more or less)…
When I define rollershutters using the depreciated [“WindowCovering”] tag, everything works fine.
When I define rollershutters using the new metadata notation {homekit=“WindowCovering”}, the blinds won’t show up in homekit.

Is this normal? Or is there something else I need to change?

Thanks,
Boby

homekit=“WindowCovering” should work.
here is an example from my test config

Rollershutter window_covering "Window Rollershutter" {homekit = "WindowCovering"}

which version of binding are you using?
