There are 2 bugs. The 11 meal and 41 meal badges aren't working, but the 101 meal one is. I'm not sure if the 503 meal badge works, because I'm not positive if I've reached that amount yet.
The 101 meal eating badge might trigger when you eat 101 meats. It's a reported bug that's been around as long as badges have been, unless they fixed it more recently.
