Settlement development: shops, etc. (Fallout 4)

Such a question: has developed to the required level of a leader, built the first store. Medical (hospital shop). It stands empty. In construction mode, he aimed at the settler, poked him into the store. The inscription "resource assigned" appeared, on the store now, in the "workshop" mode, not a red, but a green man is displayed - like, all the rules. But the tent is still empty, no one came into it to bargain, the seller did not get up and there is no goods in it. ???
