The profile wizard does not ask about private patterns, and saving an edit wrote a new file from its answers alone, so the patterns that keep a client's names and host names away from the model were removed, along with the profile's version, free text and fields of your own.
An edit now keeps everything the wizard does not ask about. If you edited a profile with private patterns in an earlier version, open it and check them, or restore the .yaml.bak saved beside it.
