Since updating to 1.18.2 version of SophisticatedBackpacks I can no longer quick add items to the crafting table in a backpack. The button isn't even there.
However the button still exists in all other crafting tables I have checked.
Double checked and have the latest of sophisticated backpacks and core, as well as JEI.

Minecraft version 1.18.2
Forge 40.1.31
Sophisticated Core 0.2.6.30
Sophisticated Backpacks 3.17.2.588
JEI 9.5.5.174

that's because you have version of JEI that's more than 2 months old. just update to JEI version 9.7.0+ (first such release was 2 months ago)
