can't find my notes

morning’ i thought maybe like this i can get a quick answer before the day is over

i worked on my i pad with the pencil and edited about 90 pages of a 425 page acrobat pro document, now i get the document, without the notes and signes.

sometimes when i open it i can find the notes in a separate column,

how can i get all the notes back in the document?  how can i ensure that it always stays like that also when i send it to other people and move from ipad to imac and vice versa?

where are the rest of the notes?
