icloud keychain

Hi all, sorry for my english.

I have this issue with iCloud keychain on my MacBook Pro 2017 (HighSierra)

I've added two Ldap Internet Account by mistake.

When I delete these accounts (with the minus button) after a couple of second they reappears (as disabled).

If i deselect KeyChain from my iCloud option, I can delete them and they do not appears anymore.

Anyway if I select again KeyChain from my iCloud options they appears once again 😟

It is possible to remove there entries from iCloud KeyChain or I have to keep this option off?

Thank you
