It's not weird at all. I measure my weight loss not only by the scale, but by how many fat rolls I have to hang on to and how many inches I can pinch. I have lost 37 pounds and I still have a belly (probably always will after 2 kids), but I feel better about my overall progress. No one, aside from perhaps surgically altered models, have perfect bodies.
If you're really concerned, you could try some target toning exercises for that area and that may help. However, you have made incredible gains in your weight loss journey so be proud and celebrate. I guarantee you look amazing!!!!!!!
