Huge weight difference in box squats vs regular squats

I’m more used to doing box squats in general but the weight difference between both lifts is insane. I can do 275 lbs on box squat for 3 reps but can barely do 150 lbs on regular squat for a couple reps. I’m 115 lbs. Would it better for me to focus on regular squatting for now or continue with box squats
