cannot sell cargo

Hi folks,

have no idea if anyone still plays this abandoned project, but if so, please tell me if in the Unstable Space alpha it is possible at all to sell cargo. I bought a pod of Aluminium at a mine, flew to a Facility with demand for that and DANG! I don't see the pod in the selling UI.

I was close enough to the station, I tried with the pod docked or undocked, to no avail.

Any tips would be appreciated,
