Thank you very much for the file!
After checking it, I found out that 2D elements on the Master Layout "22x34 w/ grid" and "22/34" are placed outside of the paper's border, as can be seen in the attached screenshot below.
The paper size define its border when exporting to PDF. If you want to include the 2D elements of the current Master Layouts, you need to enter a larger paper size, or move the elements inside the border in order to have them visible in the output.
I hope this has answered your question. If you have any further issues, feel free to ask me again!
Have a great day!
