Latest project for Jeet (Mad Max)

Hello everyone. I put together such a thing, which means all projects for Jeet. When you hover over Jeet's turret in the map, all the checkboxes opposite the projects are green. But in the upper left corner of the screen, the inscription does not go away: "Install the last improvement for the master in the garage." I come to Jeet and run all over the garage and at close range I do not see what the last thing needs to be installed there. Before that, I kind of completed some kind of project after the completion of which an inscription appeared that it was necessary to put this project for a roof in a shelter. But how to get there ....
Who knows, please tell me
