[Tex/LaTex] Problem with bold font of capital greek letters

Question

My tex file is as follows. It prints greek letters in small and capital format. When I print a capital greek letter, it automatically becomes bold and when I use a math bold capital greek letter it turns into a black filled block. How to turn this template into normal mode?

\documentclass[a4paper,12pt,times,numbered,print,index]{Classes/PhDThesisPSnPDF}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}

aaaaaa

\begin{align}
\mathbf T \mathbf \Phi\\
\mathbf U \mathbf \Pi \\
\mathbf T \mathbf \phi\\
\mathbf U \mathbf \pi \\
\mathbf T A \Phi\\
\mathbf U A \Pi
\end{align}

\end{document}

The minimal additional files are

PhDThesisPSnPDF.cls

glyphtounicode.tex
