Why am I not a Policy Admin on my own policy?

I am so confused -- I tried to turn off "scheduled submit" in my policy but it's not there, and looking through some community posts, I think I'm somehow NOT a Policy Admin on my own policy. I'm literally the only person in my company and always have been. I created the Expensify account myself and no one else has ever had access. (In fact, I'm not even sure what a policy is or why I have one, since I use Expensify solely to file receipts and generate an expense report at tax prep time.) How on earth do I get control of my own account?
