SDK 6 not installed

This is my first time trying to develop a Tizen TV app. I installed the TV extension SDK V6 and the Emulator. When I try to create a new project with Tizen Studio I find SDK v4, v5, v5.5 but it says v6 is not installed while the emulator is version 6. I tried to delete the SDK and reinstall it but the same problem occurs and i didn't found any helpful article about it.
