Solettas

I know a lot of folks ask about this one. But here I go again. The Liberty Warehouse mission. On my trade screen where it says, "Cal, you're gonna have to deliver this yourself...", the trade requirement is 2 terraformers in exchange for 1 Hull Armor. Is it neccessary to make two trips to The Ritz? I made the first, with the solettas, and dropped it off next to the base, but nothing happened. I am tired of looking at this incomplete objective. I am just about ready to complete Act 2 but want to clear the objective screen. Any thoughts?

did you try using the trade screen?
