Not working with some anotations?

[homegourmet]

Hello ! I had this weird bug as well on Preview & tried to run your script (on the web app) to repear my PDF, it didn't find any note (I have about 40 anotations that disappeared in a 1 page pdf, this is quite annoying)
However, if I open my PDF in textedit, I find the notes in the "code" of the PDF .

This is example of code of my disappeared anotations : /AP << /N 1073 0 R >> /Contents (Insert 2 \(from - to\))

Could you help? I would really like to recover my specs doc instead of re-doing it again :)

I can't show PDF here as it contains confidential infos..
