When I want to stop a job I see this dialog:

It asks me to cancel the job, and the answers in that dialog are "Cancel" and "Yes". Does "Cancel" cancel my job? I had to think for a few seconds. 
And then the other button, on the right side, the side where I in all other dialogs expect the button that stops the current action, I see the "Yes" button. 

My urgend recommendation is to use two buttons here:
  [   YES   ]  [   NO   ]

Thank you for your attention to this matter .

Sorry for selecting the wrong component, but I didn't find out how to search for components in this dialog. The drop down only shows 100 of (wtf?) 1760 components, and I cannot even completly scroll throught the list, prefixing ui-, jenkins-, etc didn't help either so please forgive me.
