Without going into specific hands, the GiB Acol bidding system has several fundamental flaws. I’m not sure that all the problems are down to the descriptions of the bids, but something really basic is going wrong.
From worst first
Forcing bids being passed regularly
Inability to value distributional hands in response to NT openings
Bidding to game after intervention and not bidding the same game without intervention NB the intervention is totally irrelevant in most cases
Frequent discard issues when the distribution is 100% known
Picking a 50 line when there is a 100% line. This may be down to it’s understanding of the bidding/play

The robot is called Argine, not GIB. But yes, there are lots of incredibly bad flaws. There's a thread dedicated to them here.
