IEEEtran.cls 中的底部边距无缘无故变小

Question

我正在使用 IEEE 网站提供的 IEEEtran.cls 撰写 IEEE Transactions 论文。底部边距毫无理由地小于 IEEE 设置的边距（我的一位审阅者注意到了这一点）。我正在编写以下代码，

\documentclass[10pt, twocolumn, twoside, journal]{IEEEtran}

\usepackage{amsmath, amsfonts, amssymb, color, enumerate, amsthm, graphicx}
\usepackage{tikz, subcaption, cite}
\usepackage{color, xcolor, soul, bm}
\usepackage{marginnote}
\PassOptionsToPackage{hyphens}{url}\usepackage{hyperref}
\hypersetup{
  colorlinks   = true, %Colours links instead of ugly boxes
  urlcolor     = blue, %Colour for external hyperlinks
  linkcolor    = blue, %Colour of internal links
  citecolor    = green %Colour of citations
}
\usepackage[normalem]{ulem}

\newtheorem{corollary}{Corollary}
\newtheorem{assumption}{Assumption}
