I logged in to your account and I notice you are using the SparkD program. Unfortunately, you cannot access the meal plan options while using that program. The only way for you to remove that vegetarian preference is to opt out of the SparkD program and then you can go into the meal plan options and uncheck the vegetarian preference. Then you can opt back into SparkD.
I hope this helps,
