1 instead of 2

[Bbradley62]

Why doesn't North correct to 3♦? Clearly, 2♦ shows more than 4 diamonds.

Edit: I also don't know why the 1♦ bid does not include an explanation; this seemed to be happening a lot yesterday.

Presumably GIB operates under the "no double, no trouble" maxim.

 

(Yes, from my experience this sort of bidding behavior - or non-behavior - is an issue with the bot.)

Similarly, I hope North would not bid this 4♣ on a 4-card suit, despite the description:
