I've no skin in this game but if I had to guess this probably had to do with their supply chain. We complain about the turnaround time for these figures and in order to address that it means companies like InArt need to give their suppliers final design approval sooner. Given the intricacy of the suit design it seems likely that (in terms of delivery) it's a long lead item for them, so despite their still soliciting feedback ANY changes to it might already have been considered too late, as scrapping what was already in the pipeline would have been cost prohibitive. Plus they probably were confident that the vast majority of customers would overlook minor inaccuracies given the overall quality of the product.
