It was found that text disappeared from book and quill after writing in it and signing it on our current bedrock 1.17 realm, leaving behind a completely unedited, unsigned book.

Steps to Reproduce:
1. make a book and quill
2. write text in the book
3. create title and label author of the book

4. sign the book

5. open the book

Observed Results:
Upon opening the book after signing, the text will be gone and the "sign" button will show up under the page again as if the book was never used or signed.

Expected Results:

The book should display the previously written text and be un-editable.
