After signing a book and quill, all the text on the first page is deleted

When I’m trying to write in a book and quill, I usually write a lot, that takes me a lot of time, and usually on three to four pages. So earlier today, (and this has been going on for a few years,) I’m writing, hoping this won’t happen again, and when I’m done, I sign it, and hopefully it won’t swap the name and author again, (which was another issue I’ve had that doesn’t appear anymore,) and then when I go into the book, the entire first page is gone, and the rest of the text is usually fine, if not with random words censored. It’s really annoying. Basically, all you have to do to recreate this issue is just get a book and quill, fill in two to three pages, and then sign it. After that, the first page should just disappear, and leave the rest of the text fine, if not glitched, or censored. That’s all. Thanks for taking the time to fix this. (This is on my Realm, by the way.)
