remove few lines from the pdf version on the first page of my thesis but still there

Question

In my thesis, in overleaf, I use my university thesis as document class. In the fisrt page there are command for head of school and nominating professor which I want to remove them. But when I deactive the command by % and recompile the document they are not removed still there with other words in pdf version. Just wondering if you could let me know how can I remove them? for example:

\headSchool{Prof. Mike Niki} % vice provost name 
\nomProf{Dr Adam Woods}

I tried this (even I removed them)

% \headSchool{Prof. Mike Niki} % vice provost name 
% \nomProf{Dr Adam Woods}

When I compile, in the PDF version this can be seen:

Head of School: Prof. Thom Jackson Nominating Professor: My Nominating Professor

Answer 1

Instead of commenting the lines, try

\headSchool{ }
\nomProf{ }

that is, with an empty space between the brackets. It's likely that Thom Jackson and My Nominating Professor are the default values of the commands.

Answer 2

Perhaps try deleting all of the auxiliary files (e.g. ending in log, aux, dvi, lof, lot, bit, idx, glo, bbl, ilg, toc, ind, out, blg, which is pretty much everything that doesn't end in tex, albeit with a few exceptions), and then recompiling. Most IDE's (such as TexStudio have a button for this in their Tools tab).
