I live in a forsaken land where my problem is exactly the opposite. I can't find BJJ belts anywhere, only solid color belts, although in my case, my belt kinda lacks that whole "color" thing. I had to get my grandmother to sew that fancy black patch on the tip of the belt, and she didn't get it quite right.
Can't you hack the little patch away? If it's sewn on, you can probably do it. It's a lame advice, but might work.
