MC1.20.1,tweakeroo 0.17.0,There are the same items in the shortcut bar, such as two sets of oak steps. After using them, even if there are still oak steps in the backpack, they will not be automatically replenished.

The above is when the block quick placement mode is turned on. If it is turned off, it is normal.

Is this on a server? There might be anti-cheat that prevents quick restock actions, or it might just be the latency to the server that causes an inventory de-sync and then the restock fails. Does it work in single player?

This problem occurred in single player mode last night, but it did not appear today.
