Trying to update app in my app store, and I keep getting incorrect password
I am trying to update an app in my app store, and when I enter my password it says it is incorrect. After I go to reset the password, I see that the apple ID is actually my mom's email, though I have my own apple account. My app store is not even logged into my mom's, because when I go to my account, I see my actual email. I'm unsure why her email comes up when I try to update certain apps. How do I get this to stop happening?
iPhone 11, iOS 14
