Latex/Overleaf PDF sections are not referenced to respective page numbers

I tried describing my sections inside a main.tex file and the corresponding sections using

1. subfile{section1.tex}
2. /input{section1.tex}
3. /section{section_name} described inside the section1.tex file and also in the main.tex

... but all of these attempts would link/refer the sections to the first page of the downloaded PDF. I need them to be referencing the respective page numbers. Subsections are correctly referenced.

PDF header

Edit 1:

It is this template. Here all the sections are written in AAStemplatev2_0_6.tex file, while I intend to have separate .tex files for different sections and call them in a main.tex file. Unable to have the sections referenced to the correct page in the corresponding PDF.
