Ruler not working on apple pen on a pdf

Hi, I am having an issue with using the ruler function of the apple pen on a .pdf file saved in my files. When I enable and position the ruler as always, the 'ink' does behaved as if the ruler is off. I've used ruler before and I don't know what's causing the issue.
