So i was testing these cool features when i suddenly found this bug
how to recreate:
1. Place a chiseled bookshelf
2. Place a comparator beside the chiseled bookshelf
3. Put any kind of book in the chiseled bookshelf
4. Lastly remove the book from the chiseled bookshelf
and you should see the results thank you

The redstone signal is based on which book you interacted with last. So when you take the last book out of a chiseled bookshelf, it detects a redstone output of 1.

Related to this bug for Java edition here: MC-256486
There's a bit more discussion over there, but agree that this is really bizarre and makes it difficult to be useful as you can't detect a change to the first/last slots. Knowing the last interacted book would only be interesting if you could interact with individual slots.

Thank you for your report!
However, this issue is Working as Intended.
The report you have submitted is working as intended: The chiseled bookshelf emits a redstone signal depending on the last interacted slot. When emptying the bookshelf the last interacted slot is slot number 1, therefore we still have a comparator signal. The only time the bookshelf has a comparator signal of strength 0 is when it is just placed. After that there will also exists a last interacted slot in the bookshelf.
Please note, that mechanics of the game may change between updates.
Things such as graphics, sounds, world creation, biomes, redstone, villagers, and animals may not work the same in current versions.
