Wares GUI - expansion wares have no 'Vanilla'

[Phezzan]

Repro:

• have an expansion installed: "Kingdom End"
• Run the GUI
• open wares
• select Object, Vanilla, Diff.Patched
• open food -> container -> BoFu
• Observe BoFu lacks any 'vanilla' values

Expected:
BoFu 'Vanilla' column should show unmodified values from ego_dlc_boron
