The reference number of my subfigure is incorrect compared to that of the main figure

Why my subfigure references increase by 0.1 when I force my main caption to be at top of figure?

This is my my documentclass{tdiinpe.cls} link enter link description here

I want my all caption (figure and subfigure) to be at top of the figure.

\documentclass{tdiinpe} \usepackage[caption=false,position=top]{subfig} \usepackage[subfigure]{tocloft} \usepackage{float,graphicx} \begin{document} \begin{figure}[H] \centering \caption{My main caption (\ref{fig:foo}) with first \ref{fig:foo-1} subfigure and second \ref{fig:foo-2} subfigure.} \label{fig:foo} \subfloat[My first subfigure] { \includegraphics[scale=.4]{example-image-a} \label{fig:foo-1} } \subfloat[My second subfigure] { \includegraphics[scale=.4]{example-image-b} \label{fig:foo-2} } \end{figure} \end{document} 

Some of the contents of tdiinpe.cls

Caption setup

\renewcommand{\captionlabeldelim}{ -} \renewcommand{\captionfont}{\captionlabelfont\mdseries\captionsize} \renewcommand\@makecaption[2]{% \vskip\abovecaptionskip \captionlinewidth\hsize % \realcaptionwidth\hsize \def\captionlabel{#1}% \def\captiontext{#2}% \usecaptionstyle{\caption@style}% \vskip\belowcaptionskip \gdef\tamlabel{\captionlabelfont\captionsize#1\captionlabeldelim\captionfont\space} \gdef\tamtexto{\captionfont#2} } 

Some of packages used

\RequirePackage[hang,small]{caption2} \RequirePackage{amsmath,amssymb,amsthm} \RequirePackage[caption=false,position=top]{subfig} \RequirePackage[subfigure]{tocloft} 

Your code get me this refence when I consider my tdiinpe.cls

\documentclass{article} \usepackage[caption=false,position=top]{subfig} \usepackage[subfigure]{tocloft} \usepackage{float,graphicx} \begin{document} \begin{figure}[H] \centering \caption{My main caption (\ref{fig:foo}) with first \ref{fig:foo-1} subfigure and second \ref{fig:foo-2} subfigure.} \label{fig:foo} \subfloat[My first subfigure] { \includegraphics[scale=.4]{example-image-a} \label{fig:foo-1} } \subfloat[My second subfigure] { \includegraphics[scale=.4]{example-image-b} \label{fig:foo-2} } \end{figure} \end{document}
