I am using the two-column format of the latex template provided by Springer( https://www.springer.com/gp/livingreviews/latex-templates ). To break longer citations I am using "breakcites" package. I use a bibtex file.

When I cite any paper with three or more authors (say author names are A,B,C with the publication year 2015), the citation comes out as:

This is the sample to show citation [A et al.(2015)A,
B, and C] which has 3 authors, [M and N(2005)] hav-
ing 2 authors, and [H(2010)] which has 1 author.

Here's the corresponding code snippet:

RequirePackage{fix-cm}

documentclass[twocolumn]{article}          % twocolumn

}

usepackage{cleveref}

usepackage{breakcites}



begin{document}

This is the sample to show citation cite{A2015} which has 3 authors, cite{M2005} having 2 authors, and cite{H2010} which has 1 author.



% BibTeX users please use one of

%bibliographystyle{unsrt}  

bibliographystyle{spbasic}      % basic style, author-year citations

%bibliographystyle{spmpsci}      % mathematics and physical sciences

%bibliographystyle{spphys}       % APS-like style for physics

bibliography{tempBIB}   % name your BibTeX data base



end{document}

% end of file template.tex

and the BIB file:

@article{A2015,

abstract = {XYZ.},

author = {A and B and C},

doi = {DOI},

isbn = {1234},

issn = {5789},

journal = {someJournal3},

keywords = {keywords},

number = {1-2},

pages = {100--110},

publisher = {somePublisher3},

title = {{someTitle3}},

url = {someUrl},

volume = {1},

year = {2015}

}

@article{H2010,

abstract = {XYZ.},

author = {H},

doi = {DOI},

isbn = {1234},

issn = {5789},

journal = {someJourna2l},

keywords = {keywords},

number = {1-2},

pages = {100--110},

publisher = {somePublisher2},

title = {{someTitle2}},

url = {someUrl},

volume = {1},

year = {2010}

}

@article{M2005,

abstract = {XYZ.},

author = {M and N},

doi = {DOI},

isbn = {1234},

issn = {5789},

journal = {someJournal1},

keywords = {keywords},

number = {1-2},

pages = {100--110},

publisher = {somePublisher1},

title = {{someTitle1}},

url = {someUrl},

volume = {1},

year = {2005}

}

The output desired is the following:
This is the sample to show citation [A et al.(2015)] which has 3 authors, [M and N(2005)] hav-
ing 2 authors, and [H(2010)] which has 1 author.

Thanks.

I was also having the same issue and as per the comment, I used usepackage{natbib} at the beginning of the document.
The issue was resolved.
