Describe the bug
Following update from 407 to 420, Easy Transfering duplicate item when pulling from SBP, and inserting just don't work

To Reproduce
Steps to reproduce the behavior:

1. Open backpack
2. Click on Quark Easy Transfering Button
3. Nothing happen

Expected behavior
To work as intended, it did before

Versions
MC 1.16.5
Forge 36.2.19
Quark 2.4.321
Buncha others

Duplicate occur for all items that are pullable: everything it can starting from the last on regular Click, only what is in player's inventory on Shift-Click

yup, looks like trying to prevent deletion of items in sorting makes the restock logic duplicate items because it doesn't check if it was able to extract items from the backpack's inventory

I am going to replace the Quark logic there with my own so that it would not only not duplicate and properly extract but that it would also work the other way around

Latest version on CF fixes this - the buttons now do what they are supposed, just keybinds won't work which is a limitation I cannot work around without having a change made in Quark.
