Additional material channels not appearing in VRayMtl Node

[TeaspoonVFX]

Hey! This is probably totally user error, but...

When working with a VRayMtl node, I'm not getting any more input arrows when I activate a map channel by toggling the checkbox in the properties.

What am I overlooking?

Seems quite strange

What build are you using, OS, Nuke version?

If you make a new VRayMtl is it working?
