I play by assembling the minecraft version 1.16.5. I did not assemble the assembly myself. What exactly is the problem?
I activate the scroll (Shift + PCM) - it absorbs experience when put on.
I change the mode (just PCM), but instead of giving away the experience, it's just... turns off.
Illustrative example: the scroll is inactive. I press Shift + PCM - the mode immediately changes to absorption. Then I click on the PCM (as it is written in the description) and the scroll is executed in the "Inactive" mode, it looks like I pressed Shift + PCM. No matter how hard I tried to activate the mode, with which it should GIVE experience, I could not. And I don't know what to do..

If someone knows how to solve this problem, please tell me T-T
