Google Password Manager not letting me delete a saved password

Wait 5 sec.

I'm trying to delete a saved account from Instagram when I'm trying to log in, and it says that the account is saved through Google Password Manager. However when I check Password Manager, the account doesn't show up on the list. I already tried deleting all passwords that I have saved on there, but for some reason the account that I'm trying to delete keeps showing up. If someone could help me figure this out so I can delete the saved account that would be terrific.
