QC Complete Error Message

Summary:
I am trying to setup vendor QC for specific items from vendors. I'm using Verify Total Count in the for the verification question. When receiving PO the process works as expected and the LPN gets located to QC location with status of Quality Check.

When I execute QC Complete transaction on the RF I enter the LPN and select the verification question. I'm prompted for the SKU which I enter but then I get this message:
"Cannot capture the qty in QC for additional invn attributes"
The screen then refreshes and re-prompts for SKU. If I ignore and enter ctrl-P to approve the LPN I get a message that verification question was never answered.
