I'll ignore the fact that it isn't obvious what '20190927.6' is from the screenshot (it would be more obvious in the workflow context).
Obviously someone is following the pattern that the primary button should be labelled clearly as the effective outcome - in this case, clicking on the primary button should result in '20190927.6' being cancelled.
They've also included a secondary button which backs out of the process without making changes - labelled 'Cancel'.
Luckily, there's a design convention - so the blue button is probably the primary action, and the grey button is probably the secondary.
What would be a better way to label these buttons?
Given the 'are you sure' question, wouldn't Yes/No buttons be good enough in this instance?
