Record button is missing from Logic Pro X project file

My friend created a project in Logic Pro and sent it to me. It is an insturmental remix of a song. I am however not able to record anything as the record button is missing. It is apparent that he did not tick the "Record Enable" box when the project was created, thus I am not seeing a record button (unlike the other projects I create, where as the button is clearly there) in this project file.

I can't for the life of mine figure out how to get the record button visible in the project. I've read that one should go to "Preferences" and choose the right microphone input device, but it is already the correct input. I am even seeing that the dB parameter is moving up and down, due to noise from the microphone. How do I get the "Record" button?

Help, anyone...
