I need to add an external project to an Xcode project, so I need to add a target dependency for a static library of external projects.
I can not add it as I need, I would like:

However, when I add another project to my actual Xcode project, I get the following, which prevents me from exploring this project from mine, and therefore I cannot add the dependency I need.

Please note that these screenshots are taken from two different projects, and in the one that shows me what I want to reproduce in my own project, dragging and dropping several projects works as expected.
Perhaps I have some settings that were configured incorrectly in my project? All I did was make a master template application from Xcode.
