No option for Titanfall Multiplayer Campaign

I recently purchased Titanfall and love playing the multiplayer mode, but there is no option for campaign mode. I've watched others videos and when they log in online there is an option to play campaign or classic and mine does not show either. I am on a PC and when I launch the game the only option given to me is "Play". When I click on that it connects me to the matchmaking screen and the next screen is a Lobby with only and option of "Play Titanfall", at which point it allows me to select from the various game styles. I know there is no single player campaign, but I just want to play the multiplayer campaign. Where is this option? This should not be the beta since I purchased it from Origin so I'm confused why this is happening. Thanks for the help!
