So i was playing around with the new bookself and when i have all 6 books off it gives on a power level of 1

so how you gte this is buy setting it up to a comparator and then you wanna put a 6 pices of redstone in a row and every other put a repeater so like put a reapeater switch siodes then another make sure no 2 ever touch or it looks wierd and then you put in the books in order from 6 5 4 3 2 1 im not 100% if this is a bug or intended jsut seems confusing becuse there 6 filled and only 1 left you can put the books in any order and take them out in any order aswell one picture is the bug the other is the setup this is on a server so it may be fine on other servers
