Error Message when Using Section and Subsection in Titlesec

Question

I have converted a .docx file to .tex, and I am trying to create a running header. Looking through the forums, I have found some nice code to generate this header. Unfortunately, when I try to implement the \section or \subsection feature, I receive multiple errors.

At the moment, the header has 0:00––0:00, showing that it has been created, but I cannot actually create the section and subsection environments. I have attached my preamble, so that you can see if there is anything that I have overlooked.

EDIT: I have updated the question with an excerpt here.

I have attached some images for the expected output. This image shows the header that I am going for. The only difference is that I do not want a header on the first page. I would also like the English title to be on the odd page and the Syriac title to be on the even page.

Below is the current output.
