This hand is from Arena Challenge.

4♦ says " 5+♦,4+♥,6-32hcp,7+TPs".
5♦ also says "... 6-32hcp...".

6-32hcp? Too wide range, actually it is impossible.

I suggest to take "32" as a joke but on the whole I agree. Since 3♦ is already forcing and showing diamonds (at least that's how I play it), 4♦ should be a very specific bid. Apparently it means "I don't want to play NT and I'm not sure if we can make 5♦" and if that's the case it should be labeled accordingly. It is similar to what I posted a few days ago: It should become clear from a label if a bid is "to play" or "forcing" because it cannot be both (and if it is "to play" partner should not raise with a minimum hand). The programming part of this is of course very complex in high level bidding.

By the way the 5♦ label can be explained because it shows keycards and takes the shape and range from the previous bid. I agree with you there's a contradiction because if the player has only one keycard he can't have 32 HPC .

Although the explanation is wrong, 5D was a blackwood response.
