I guess the group's axes' directions and the model's axes' directions differ ?
Try exploding the group in place and immediately regrouping it so the axes reset, re-dimension and see if the dims are then fixed...
If it's a component then you can try resetting the component's axes to mimic the model's axes directions etc.
😕
indeed, the axis were different. But I'm thinking now that the cause was a earlier mirroring, because after exploding/regrouping I changed the axis again, and everything stayed in place.
