Misterious Service Providers has been appeared with the update

I've just update de plugin. I have two Service Providers, Dr. Jose M del Amo and Dra. Olatz Alcelay. These are well configured in Settings. But... In the front end and in the back end Dr. Jose M del Amo has been substituted by "Sanchez, Elena" and Dra. Olatz Alcelay by "Xavier Elorriaga". And the worst ... ¡¡¡I don't know who they are!!!
