"Find Item" Releases Token Without Locating an Item

I am working with a warehouse model where items (boxes) need to be retrieved from a storage area (racks called "grillage") based on customer orders. The initial stock is placed in these racks, and the "find item" function is supposed to identify the requested item (SKU label) in a specific slot (slot type label).

However, at timestamp [2522.00], the "find item" function released a token without an actual item being present.

How is this possible?

You can find please the model attached: 300125 - MODELE V1 FORUM.fsm

Processus: " preparation entrepot"

Software Version:

FlexSim 24.0.6

The tokens leave the Find Item activity around 1900s. At that point the items still exist. In another Find Item activity, "Mark Item as Outbound" is not checked. So the items were likely 'found' a second time but the first process had already moved and deleted them.
