In my signature list appears a signature with “synced with gmail”. I tried everything to get rid off that signature, but I’m unable to delete it. I have not the permission to delete it in emClient and after deleting it in GMail (web) it apppears after a short time 
Do you have any idea, how this problem can be solved?
emclient Version 10.1.4588
Having the same issue.
If a Gmail signature is still appearing in eM Client automatically, then sounds like it’s still on the Server end in Gmail Settings online as eM Client.
Dblcheck that it’s completely removed in Gmail Settings as per the following Google page info.

(Remove Gmail online Signature on computer)
“Open Gmail”.
“At the top right, click Settings and then See all settings”.
"Under “General,” scroll to “Signature.”
“Click the signature you want to remove”.
“Click Delete and then Delete”.
“At the bottom, click Save Changes”.
If the Gmail signature is definitely completely gone online in Gmail Settings, then “dblcheck eM Client Signatures and Templates” to make sure it’s not setup in there as a eg: Local Signature or Local Template as per the eM Client support page. Also that it’s “not selected” in any fields.
