Hi,

in der offi. Wiki findet man folgende Info hierzu:

"There is a known bug where the Advanced Workbench engram will not appear in the smithy, even if engram points were spent on it. This bug currently happens on PS4 and Xbox. Cheating in the item doesn’t seem to give you the item either, at least in PS4. On Xbox using the admin cheat code like so: GFI AdvancedWorkbench 1 0 0 :will force give you the advanced workbench in your inventory. This appears to be currently the only way to get the item."

Es ist also ein bekannter Bug und die Workbench muss ercheatet werden.
