Command books

I use datapacks to create games and the command books are all messed up

What I expected to happen was...:

Command books to execute commands by clicking on the buttons

What actually happened was...:
The command books just display jibberish as you can see in the screenshots provided

Steps to Reproduce:
1. Place down a command block then paste this code item replace entity @a[gamemode=creative] hotbar.8 with written_book{pages:['["",{"text":" Battlefield","bold":true,"color":"dark_blue"},{"text":" v2.31","bold":true,"color":"blue"},{"text":"\\n","color":"reset","bold":true},{"text":"Only click Prime when ALL players are on the server","bold":true,"color":"dark_red"},{"text":"\\n","color":"reset"},{"text":"-------------------","color":"black"},{"text":"\\n","color":"reset"},{"text":"       1.

2. ... Power the command block
3. ... and the book it gives you just displays jibberish in versions 23w40a & 23w41a (Works perfect in 1.20.2)
