If you made the same project in the web version I will be able to see it and tell you exactly what is going on. It can be imported also from .mq4 file (the one generated with fxDreema).
When you type the new block title, click on it to confirm (this works as some invisible button "OK" is clicked). When the name is edited successfully you should see new event in Actions History and also a message up there, below the menu.
