Based on previous posts, I would guess GIB thought you might only have 1 keycard.

Obviously Gib got count wrong.

You mean the human right? :unsure: 4NT is really bad but at least you still reach a slam if the human responds properly.

You responded showing 1 or 4 KC with 3 keycards. I'm gonna be blaming you for this one. GIB knows you can't have 4 keycards (it has 2) and so relaxes in the perfect contract - 5!D.

It is in fact quite clear what suit 4NT is keycard for. It's your last naturally bid suit. Of course, it's also given in the description that GIB provides for 4NT. If you have difficulty viewing that (for example on some mobile devices), then you can try mousing over 5!S as a response - it'll tell you what queen you promise when you bid it, and thus what suit you're answering keycard for.
