Actions not showing?

Hey everyone
In one of my resources the actions are not showing.
I can not find out what I'm doing wrong, though it is probably something...

Solution

It was the content grid I was experimenting with at some point:

->contentGrid([
                'md' => 2,
                'xl' => 3,
            ])

->contentGrid([
                'md' => 2,
                'xl' => 3,
            ])

removed it and the buttons are back.
