Yes, I get this too. I have two email accounts in Evolution, one for home and one for Work. I have created signature named 'Home' and another named 'Work'. If I create a new home email I just get the Home signature. If I reply (or Group reply) to a home email, I get 2 Home signatures. If I create a new work email I get a Work signature followed (underneath) by a Home signature. If I reply to a work email I get 2 Work signatures and then a Home signature!
