You can see the bot says that my 3NT shows 25-32 HCP and apparently it believes it because it jumps to 6NT with an ace and a king.

Given that the opponents have opened the bidding, having a bid in this sequence that shows 25-32 HCP doesn't seem all that useful

What do you think it should say instead?

An immediate 1NT is 15-18, slightly wider than a 1NT opener as per standard; if you think your hand is stronger, then double and 2NT over 2♦ shows 19-21.. double then 3NT over 2♦ has been programmed as 22-25..

From its perspective you're simply making an impossible bid.. when a human makes a bid that isn't defined at all, it falls back to the lowest level rules of thinking game requires a combined 25 points, and slam requires 33. Your partner has shown 0 points and could easily have a yarborough, so if you still want to play in game and not slam opposite that, then that means your impossible bid must show...

Agree, 25-32 is a pretty unusable range. I play 30-35 in that sequence.
