# Wrong name separation in latex bib [duplicate]

I've found here how to write author's names in latex bib. However, the first author name is always separated in two with a comma. Here is an example:

@conference{ASoDToED,
title = {A Study on Deduplication Techniques over Encrypted Data},
author ={Ganesh,Amal and Sunitha,C. and Akhila,K.},
year = {2016},
booktitle = {procedia Computer Science},
volume = {87},
pages = {38 to 43}
}


As output i will have:

Ganesh, Amal, C.Sunita and K.Akhila


And it's the same for ALL my bibliography: the first author name is splitted with a comma. I've tried many other ways, like writing:

Ganesh,A. and...
Ganesh Amal and ...


It doesn't change anything.

However, the reference is good. For the example i gave here, the reference is [GSA16], which is the good one. So it didn't consider "Amal" as a name, but it still write it separately with a comma... How can i get rid of this comma? It feels weird that the first name is not written as the other ones.

EDIT: Here is a minimal example. The documentclass wissdoc can be found on GIT.

\documentclass{wissdoc}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{bibgerm}
\usepackage[
numbers,
sort&compress
]{natbib}
\usepackage[protrusion=true,expansion,babel=true]{microtype}

\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amsfonts}
\usepackage{dsfont}
\usepackage{moreverb}
\usepackage{subcaption}

\begin{document}

\graphicspath{{images/}}

\selectlanguage{english}
\chapter{first Chapter}
let me introduce the chapter
~\cite{ASoDToED}
\section{first section of chapter 1}
this is my text
~\cite{SDoED}
\section{second section of chapter 1}
i have a lot of sections

\bibliographystyle{geralpha}
\bibliography{textest}
\end{document}


The bib file:

@conference{ASoDToED,
title = {A Study on Deduplication Techniques over Encrypted Data},
author ={Ganesh,Amal and Sunitha,C. and Akhila,K.},
year = {2016},
booktitle = {Procedia Computer Science},
volume = {87},
pages = {38 to 43}
}
@article{SDoED,
title={Secure Deduplication of Encrypted Data: Refined Model and New Constructions},
author={Jian, Liu and Li, Duan and Yong, Li and N., Asokan},
year={2017},
}

• Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – DG' Oct 20 '18 at 19:18
