Are you using kbin on mobile? I'm thinking maybe you're not able to see the side bar. I'll copy and paste the section regarding lables over here so you can take a look:
_Titles - Submission titles must match the source title except for the use of all capital letters. All caps titles are not permitted. Titles must include a label indicating News, Opinion/Editorial (pick the appropriate one), Analysis, or Discussion.
Glossary of terms: Editorials have author bylines that denote a collection of people within a news organization, such as candidate endorsements from a newspaper’s staff. Opinions have author bylines from a single (maybe two) writer(s). Analysis is when an author starts with factually verified current events and reports then explains deeper significance or motivation, predicts future outcomes, or makes a policy recommendation based on the starting data._
