Concrete block cargo dissapeared

Location: Yukon, Flooded Foothills, Railway Station
Truck: Azov 73210
Frame addon: Sideboard Bed
Trailer: Sideboard trailer (2 cargo spots)
Mission: Reinvigorating the old mine

I moved THE LAST concrete block on the map with crane from loading spot on top of a cargo of metal beams in sideboard bed (truck frame) as the crane is too weak and short to move it all the way back to the trailer. To pack the last cargo I needed to complete the mission, I unpacked all cargo so that I could try to force the concrete blocks to be packed, but when I clicked "Pack cargo" the concrete blocks cargo dissapeared!

Craft a new block on flooded foothills. Unlimited cement there plus a crafting site for concrete nearby.
