I’ve made 2 accounts and they’re still on my credits.

Hey so I’ve made a second IMDb page (Jeremiah Bovey II) to make another one Jeremiah Bovey-Knight for a credit and my old credits are still attached. There’s 2 Jeremiah Bovey’s and I’m wondering if I can remove the Jeremiah Bovey (I) from the credits Real With You and Unseen.
