Haven't seen this kind of goof-up before from Gib.
Seems normal to bid 4♠ over 1NT.
Looks like responder can see 6-2 ♠-fit and has 14TP vs an opener...
At other tables, they responded 2NT instead of 2♦, and Gib then jumped to 4♠.
The only difference I could see in descriptions was
2♦=12-13HCP, while
2NT=12-14HCP

An excellent description of GIB's hand.
1) 4+ spades - Check
2) 11-12 HCP - Check
3) 12+ total points - Check
Unfortunate that the patient died

It's true, in my experience I'd expect GIB to find the way to 4S on a hand like this. As you said the normal bid is a jump to 4S over 1NT, but GIB rarely if ever chooses this call.
A similar auction GIB handles poorly is 1m-1H-1S when responder has 4 spades and 13-14 or so. Once again the normal action is a jump to game, but GIB will typically bid 4SF before raising Spades. Apparently the original programmer wasn't aware that this auction shows extra values, and BBO has never changed it.
