Hinton: You are almost certainly missing the include for the Dock. With Pieces, this line of code is at the very end of eq2ui_inventory_inventory.xml so users don't need to replace the parent file. Technically this isn't legal XML, but it works.
With the full sets, its contained in eq2ui_inventory.xml (legal XML). If you installed just the eq2ui_inventory_inventory.xml from a full set, you'll need to add the following code to eq2ui_inventory.xml
Code:
<include>_Fetish_inventory_dock.xml</include>
