When will they have IT systems working properly

I'm trying to use the RTW planner on Skyteam site. After you have entered your city of departure, it is impossible to add cities. When you click on the + sign, it's just emptying the field with the 1st city. So annoying...

I tried from a Mac, from a PC, from a tablet, different browsers. Nothing works.
Does any of you see the same bug ?
