Signals Notebook: Warning message displayed when attempting to delete an empty location from Inventory

When attempting to delete an empty location in Signals Inventory the following warning is displayed: "Cannot delete location". This can happen when there are 'FINAL_DISPOSED' containers associated to that location. To identify them follow these steps:
1. Log into Signals Inventory as an administrator
2. From the username menu select 'Disposed Items'
3. In the 'Status' filter select 'Final Disposed'
4. Use the 'enter text to search within results' text box to identify containers associated to the location

Solution: Move the 'FINAL_DISPOSED' containers to another location using 'Move Location Content' even if the location seems empty and then delete the location.
