Springer Nature: use multiple references

Question

Here is the Springer Nature template. I can't add multiple references in this format: [1-4]; instead it is adding references as [1,2,3,4]. Here is my reference code.

\cite{de_florio_physics-informed_2022,de_florio_physics-informed_2022-1,aliakbari_predicting_2022,abueidda_enhanced_2022}

and here is the output.

If I include \usepackage{cite} I get lots of errors in the document.

ADDING ADDITIONAL INFORMATION:

I am adding the whole preamble.

\documentclass[pdflatex,sn-basic]{sn-jnl}
\usepackage{array}
\usepackage{float}
\usepackage{xcolor}
\usepackage{subfig}
\jyear{2022}%
\theoremstyle{thmstyleone}%
\newtheorem{theorem}{Theorem}%  meant for continuous numbers
\newtheorem{proposition}[theorem]{Proposition}% 

\theoremstyle{thmstyletwo}%
\newtheorem{example}{Example}%
\newtheorem{remark}{Remark}%

\theoremstyle{thmstylethree}%
\newtheorem{definition}{Definition}%
\providecommand{\tabularnewline}{\\}
\raggedbottom

I didn't modify anything in sn-basic.bst

The code you've shown in your query does not generate numeric-style citation call-outs. Instead, it generates authoryear-style citation call-outs. I can only surmise that your document contains additional code -- possibly invoking the macros \setcitestyle and/or \biboptions. Not being blessed (cursed??) with any usable psychic divination powers, I can't and won't speculate on what this additional code may be.

What I do know, though, is that if you (a) specify sort&compress as an additional document class option and (b) add the directive

\setcitestyle{numbers,square,citesep={,}} 

in the preamble, your document will generate sorted and compressed numeric-style citation call-outs.
