Sections in Appendices list are not idented in the table of contents

Question

The section title in the list of Appendices is not being indented, but the subsection title is indented. So, for example, the outline of Appendices in my table of contents looks like this:

APPENDICES

    A     Chapter Title

    B     Chapter Title

    B.1     Section Title

    B.2     Section Title

                B.2.1     Subsection Title

                B.2.2     Subsection Title

    C     Chapter Title

    C.1     Section Title

    C.2     Section Title

    C.3     Section Title

I don't really have any special code, I don't think. I need it to look like this:

APPENDICES

    A     Chapter Title

    B     Chapter Title

             B.1     Section Title

             B.2     Section Title

                         B.2.1     Subsection Title

                         B.2.2     Subsection Title

    C     Chapter Title

             C.1     Section Title

             C.2     Section Title

             C.3     Section Title

What can I do? Thank you in advance for your help.

The code I used is from this template:

Answer 1

I fixed it! I removed this:

{\let\protect\l@chapter\protect\l@section}

from this line in the code:

\addtocontents{toc}{\let\protect\l@chapter\protect\l@section}

and that fixed my problem.
