Unable to resolve these two warnings in my revtex4-2 file

Package caption Warning: Unknown document class (or package), standard defaults will be used. See the caption package documentation for explanation.

I have to use captions for subfiguers, however cannot figure out why this warning is coming

‪/usr/local/texlive/2021/texmf-dist/tex/latex/caption/caption.sty‬ A float is stuck (cannot be placed) on input line 583.

This second warning is coming at the line \section{} where I am not using any float option.

Currently using the following packages:

\documentclass[%
reprint,

amsmath,amssymb,
aps,
pra,
floatfix,
]{revtex4-2}
%


\usepackage{graphicx}% Include figure files


\usepackage{dcolumn}% Align table columns on decimal point


\usepackage{amssymb}% for tick mark


\usepackage{bm}% bold math


\usepackage{tabularx}


\usepackage[labelformat=simple]{subcaption}


\usepackage[normalem]{ulem}


\renewcommand\thesubfigure{(\alph{subfigure})}

  • The caption package (loaded by subcaption) is not compatible with revtex. IIRC you can use subfig. – campa Aug 16 '22 at 07:23
  • As @campa says, you should \usepackage[caption=false]{subfig}. The syntax for subfloats is not the same as with subcaption, but you find several examples on the site. – egreg Aug 16 '22 at 11:18
  • Resolved the issue of subfigures. However, this warning is not going anywhere A float is stuck (cannot be placed) on input line 223. where line 223 is like this \begin{equation}\label{e1} \mathrm{U}(z,T)=C \left( z^2-z_s^2 \right)^2-d \left( \frac{z^3}{3}-z_{s}^{2}z \right), \end{equation} – Sam Aug 16 '22 at 15:36
