Steps to reproduce the behavior:
Fill a double chest with Shulker Boxes

Go far away to deload the area
Use Sculk Transmitter and take a Shulker Box
Close the Sculk Transmitter
Use the Sculk Transmitter and there should be the Shulker Box you just took still in the chest

Full Chest of boxes

Linking the Sculk Transmitter

Opening the Sculk Transmitter from very far away (~5k blocks), and taking a box out

Box reappearing in linked chest

Showing all boxes still being there

Additional context:
Can be infinitely repeated
Even when going back to the chest the boxes that were duped still exist along with the original box
