Book and Quill Error - Bukkit 1.12.2

Hello, Bukkit Forum.

I am experiencing errors with Bukkit Version 1.12.2. Whenever I sign a Book and Quill, the text inside the book is incorrectly formatted with errors in the main text of the book.

My saved book titled "Hello" with 1 word "Hello" appears as: {"text":"Test"} (Example below)

I have tried vanilla Minecraft, and the book saves fine.

I also tried Spigot Version 1.12.2 and get the same error as when I am using Bukkit.jar.

I do not currently have any mods installed. There are no console errors. Server loads fine with no errors.

​

I appreciate anyone who can give me any input on this as I have searched all over the internet and have been unsuccessful in finding a solution.

Thank you,
