The repair method I described will have removed all the Google contacts from eM Client, then downloaded them again from the server. If after doing that, these fields are still there, then they are in the contact on the server, otherwise they would not be displayed.
But you can remove the Gmail account from eM Client and confirm the contact is no longer there. Then add the Gmail account back again and see what you get. That way, there is no doubt that the data is coming from the server, otherwise where would it come from?
yes – its the kernel of my question – where do these data come from
because if these data come from gmails-contacts server (where i can not
see them!!) an i delete them within em-client, they also should be deleted
within gmail during next sync - exactly as ist works with all other
data when they be changed/deleted within em-client
meanwhile i did some more investigation and for the moment it seems to me
that em-client generates these data out from the google-account directly and
the settings for alternative adresses i made there
i will do some more tests to verify that
so at this point i thank you for your feedbacks and suggest to leave
the topic on hold until there are further findings
