Bibtex: \Makeuppercase Authors har2nat Bibtex

TeXdistribution: MiKTeX 21.2

I am using bibtex& for my bibliography \usepackage{har2nat}. Changed the agsm-style (renamed it to agsm-my& changed \bibliographystyle{agsm-my}).

The 2 changes I did in agsm-my are

1. Get rid of the quote in the titles, as done here Fine tuning the agsm bibliography style, and adding links . Which gave me the expected outcome

2. I want to have all authors in uppercase. For this I inserted in agsm-my (according to Upper case author names for BST file (based on APA))

s

FUNCTION {makeuppercase}     {duplicate$ empty${pop$ "" }{ "{\MakeUppercase{" swap$ * "}" * }if$}FUNCTION {format.authors}{ author empty$    { "" }    { "{vv~}{ll}{, jj}{, f.}" author makeuppercase format.names }  if$}

(FUNCTION {makeuppercase} is located after FUNCTION {emphasize}{ [...]})but I am getting additional ands as a results between the names (see Ojovan, M. I.) & I do not want them:

What causes the and to occur & how can I solve it? Or is there another possibility to change the author names all in uppercase?
