I see your problem after checking out your speakers.
I’m surprised your dealer won’t make it right. I wouldn’t recommend re-terminating because they look precision made. Something you could consider is filing off 1/32nd off each side of the spade which will bring the spade into spec and won’t affect the conductive area.
Don’t use a file rub the spade on wet/dry paper 400 grit, practice fitting after every few sandings.
Practice on a spare spare first.
