I am preparing a manuscript to submit to MRM. They provided the Latex template but there is something odd. The author affiliations don't appear below the names in full line but they broke down in small lines. Every affiliation should be in single long line.
Here is the code
\author[1\authfn{1}]{Author One PhD}
\author[2\authfn{1}]{Author A.~Two MD}
\author[2\authfn{2}]{Author Three PhD}
\author[2]{Author B.~Four}
\contrib[\authfn{1}]{Equally contributing authors.}
% Include full affiliation details for all authors
\affil[1]{Department, Institution, City, State or Province, Postal Code, Country}
\affil[2]{Department, Institution, City, State or Province, Postal Code, Country}
I attached a photo how it looks like. Any help would be highly appreciated.
