Is UPS blatantly stealing from me? Help me make sense of this.

Received a cost adjustment notice from ebay on behalf of UPS. Reason for the cost adjustment:

Weight on label: 16.00 OZ
Billable weight: 1.00 LB

Providing a few pics to see if i'm blind and missed anything:

Anyone know how to dispute this?

EDIT: Fixed formatting

UPDATE: talked to ebay customer service on the phone. They’ll be refunding the cost difference. They also mentioned they are aware of multiple issues like this and have escalated the issue with UPS.
