Autotext greyed out.

I have SDL Trados Studio Starter. Is Autotext enabled in Starter at all? If so: I have AutoSuggest and Autotext selected under Options. When I press Alt+F7, the top left menu items in the Editor view are given little black boxes with numbers or letters, like an accessibility thing. In the Autotext window under Options, everything is greyed out except for the target language which is set to US English and can't be changed. Screenshots below. Very grateful for any assistance!
