Civilization Beyond Earth Issue

So I installed the base game and also the Rising Tide DLC. When I click on the base game in Steam it opens up the Rising Tide game instead. How do I open up just the base game? Am I supposed to install the DLC after I beat the base game? I even watched the opening scenes for both games on YouTube and it is in fact opening up the Rising Tide game instead of the base game.

If you start the game from your library in Steam by selecting the game from the list and clicking the green "PLAY" button, do you get a menu to choose which part of the game to launch? Is there a down arrow next to the "PLAY" button?

With rising tide, you select the type of game in the new game screen, IIRC. Base saves will not use the new features, etc.
