Answer 1

This issue has been addressed at Tex Stack Exchange, see here.
The proposed solution is to use the subcaption package, instead of subfig.

Answer 2

I had the same issue and found a solution here: https://answerbun.com/tex-latex/latex-how-to-remove-round-brackets-in-the-caption-of-subfigures-using-subfloat/
I used the following package:
\usepackage[caption=false]{subfig}
And the following structure:
\begin{figure}[H]
\captionsetup[subfloat]{labelformat=simple} %% Do not forget this command!
\centering
\subfloat[]{\includegraphics[width=0.49\textwidth]{fig1}}\hfill
\subfloat[]{\includegraphics[width=0.49\textwidth]{fig2}}\hfill \\
\subfloat[]{\includegraphics[width=0.49\textwidth]{fig3}}
\caption{General caption.} \label{fig:1}
\end{figure}
It worked for me!
