Reverting back from Apple Passwords

I also downloaded Apple Password, thinking I could use this is as a backup. But it has blocked my use of Password One and when I turn off Apple Password in System Settings, Password One is no longer active. Can someone help me? I would like to revert to Password One as my primary password vault and either turn off Apple Password or delete it altogether. Do you think if I just delete the app, my wonder Password One will return? Roger
