Invoices showing as Picking, even though they are already posted. 

This issue occurs when invoices are posted while the Pick & Pack setting is set to Basic Picking & Dispatch, then the setting is changed to Full Pick and Pack before those invoices are marked as Picked and Dispatched, causing them to remain stuck in the Picking status.

Workaround Suggested

• Change the setting back to Basic Picking & Dispatch.
• Open each affected invoice and mark it as Picked and then Dispatched.
• Once all affected invoices are updated, the Pick & Pack setting can be safely changed back or turned off.
