How to remove dots in LaTeX headings?

Question

TeX

I decided to make a diploma here based on this: https://github.com/welldan97/xetex-eskdx/ template.
Everything seemed to be going well, I screwed on the frame, it looks great, and in general I have good impressions from TeX.

1)))). Title

\titlelabel{\thetitle\quad}also has no effect.
