以数值形式出现的引用

Question

我在设置参考书目时遇到了问题。我使用的是哈佛引用格式，但我的引用却显示为数字，如下图所示：
super,comma,numbers如果我 删除natbib，我会得到所需的输出虽然这会导致参考书目中的参考文献编号标签消失这是我不喜欢的。以下是我的 MWE：

\documentclass[12pt,openany]{book}
\usepackage[ 
left=2.5cm,
right=2.5cm, 
top=3cm,
bottom=3cm,
headheight = 3\baselineskip,
headsep = 5mm,
a4paper
]{geometry}
\usepackage[table]{xcolor}
\usepackage{graphicx}
\newcommand\HRule{\noindent\rule{\linewidth}{1.5pt}}
\usepackage{background}
\backgroundsetup{contents={}}
\usepackage{fancyhdr}
\usepackage{hhline}
\pagestyle{fancy}   

\usepackage[super,comma,numbers]{natbib}
\renewcommand{\bibnumfmt}[1]{\textsuperscript{#1}}
\setlength\bibindent{0pt}
\bibliographystyle{apalike2}
\usepackage{etoolbox}
\usepackage{hyperref}
\hypersetup{
    colorlinks=true,
    linkcolor=blue,
    citecolor=red,      
    urlcolor=yellow,
}
\usepackage{showframe}
\begin{document} 
    
    \chapter*{Acknowledgements}
    I want this citation \cite{hapa:graphenum} to be \textcolor{red}{Harary and Palmer }\textcolor{black}{(\textcolor{red}{1973})}. I want this citation \cite{Knuth94:TheTeXbook} to be \textcolor{red}{Knuth }\textcolor{black}{(\textcolor{red}{1994})}.This text is quoted from \cite{datta2017latex} should be (\textcolor{red}{Datta\textcolor{black}{,} 2017}).
