PDF goes black after editing!

Hello everyone!

I need your help with this issue. I use Apple’s default Files app to edit my PDF documents on my iPhone and/or iPad. After taking notes on the document, and when I scroll down a few pages and return to the page that I edited, it goes blank except for the drawings that I’ve made. This problem occurs on all edited pages. Some other PDF apps have the same problem and some others don’t, I’ve dowloaded at least 20 other apps but I really like using Files app to edit some files because of the text recognition option. It also occurs in Apple’s Books app.

Is there a solution?

Thanks.

Current operation systems are iOs 17.0 - iPadOs 17.0.
