Some text of the picture in the pdf file cannot be displayed

I uploaded a pdf document and found that part of the text on a certain image was not displayed during preview. I guess it might be the reason for the font, but I finally found that it was not the problem. It seems that the text at this location could not be displayed? But this is just my guess

Of course, there is no problem opening this document after downloading

I put this document in chart-list/files at main · Janeisme-lll/chart-list · GitHub

test_ file.pdf, you can download it (because this document involves privacy, only part of the data is retained in the document, which is enough to repeat the problem)
