Remove project from Unity Ads Admin

Hi

Somehow i have 2 projects with the same name, the second comes with “(1)”
{MyProjectName}
{MyProjectName} (1)

in the Unity Ads admin. How can i remove project from the Unity Ads Admin?

Answering myself:
Unity5.2+ > Services > *then in the services tab there is this “options” button that looks like 3 horizontal lines, click it > Settings >
a) unlink - didnt work for me, cliking that button nothing happened (Unity 5.2)
b) rename project - make sure another project with such name doesnt already exist. If so, associate that project to empty/different project and rename it, then you can in turn go back to and rename your target project.
