ipad prompting to enter passcode for Other iPhone

I have a new iPad (7th gen) that replaced my iPad Air 2. I also have an iPhone 7. Both are company provided, and managed with an MDM. I have set the passcode the same on both devices. However, on the iPad, I am prompted in the settings to update my Apple ID Settings. After signing-in with my password, entering my passcode, I get another prompt that says "Enter iPhone Passcode". It wants the passcode I use to unlock my iPhone. The prompt correctly displays the name of the iPhone. After entering the code that I know is right, it says "Enter the passcode for your other iPhone, not the passcode for this iPad". Well... They're the same code. I don't see any way to continue. What do I do with this?
