No Automation button on track end

I cannot activate the automation menu as the is no button to click on under the funny looking “>”.
I wish to manually alter the levels at the beginning and end of the track.
I have the track window open. The " header" on the left end of the track does not show the option.
I am using LE7 latest version on an iMac.

I love replying to my questions.
I resolved to invisible automation button. It seemed as if the original window did not correctly open. The next day when I opened Cubase and the project file the automation button was there.
