Get rid of the un-delivered cargo (Starpoint Gemini 2)

In cargo transportation missions, I did not deliver the cargo twice. Now both cargoes are on my ship. In the "items" column. You can't sell or throw them away. They do not take up space in the hold, but one of them seems to be considered contraband. When landing on the planet at customs, you have to smear a point with Vaseline. Tired of it! How to get rid of this burden?
