Why can’t I delete items from Passwords (Keychain)?

After getting home where my "Mac mini" was, I went into "Passwords" in "System Settings.app" and I also went into "Keychain Access.app". Also, I turned on "Sync" in "iCloud Passwords & Keychain" on every device. I edited and deleted several times and eventually every entry deleted permanently. I'm really not sure what I did or why it worked. Since I could not delete entries with syncing turned off it seemed that I should leave it on while attempting to solve the problem. Note: I suggest creating a new Keychain and copying all the iCloud entries to that new Keychain. This preserves anything that you might need to access. I don't understand the relationship between "Passwords" in "System Settings.app" and passwords in settings and the "Keychain Access.app". I'm going to ask a new question about that. It would seem that some of my issues have to do with that. I think that part of the problem is this relationship. Ultimately, I think the solution was going into the "Keychain Access.app" and editing every field in the item(s) that can't be deleted, then deleting. Some of this I think is a work in process at Apple and I think these bugs are temporary. Most people will never notice these issues.

It’s never trying to fill passwords. It’s only used when creating new accounts it just suggests a user name. This feature of keychain cannot be turned off in anyway at all, in my situation; typically the only way to stop the behavior is to delete every single entry from keychain (passwords). Only 1password is setup for use. My problem doesn’t change whether or not Keychain is syncing with iCloud. Unfortunately, none of your advice applies to this situation. I only need to delete all the entries from passwords, which does not work. Three password entries refuse to be deleted. Also, when I turn off or turn on “Sync this iPhone” for “iCloud Passwords & Keychain”, nothing at all changes. The list still just has those three entries that cannot be deleted. And the old suggested user name still pops up. After adding three dummy entries with a different user name the default user name does change.

Originally when I was trying to figure out where that old user name came from, while screen sharing with Apple I had turned off iCloud syncing and then deleted every entry in passwords and the suggested user name stopped. For some reason with the latest update three entries came back and when I tried re-enabling syncing, I assumed all my old passwords and usernames would come back, they didn’t. This is not a problem, because I haven’t used keychain for many years. But what purpose does iCloud have if nothing previously synced is there. My only wish is to have no usernames or passwords in keychain at all. I will be back with my Mac later today and will see if I can do anything from that end.

Here are two screen shots:

I can't nail down the specifics. I do believe these are clear issues that they will resolve it time.
