Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting DLC tab unavailable/missing in game properties

I'm trying to install the Divinity Engine 2 Data DLC, but when I right click DOS2 and enter properties, there is no DLC tab available.

I've tried restarting Steam multiple times, opening and closing the game, and installing and uninstalling Divinity Engine 2 itself.

There are no updates available for the game. I do not have the paid DLC for the game.

Any suggestions? Thanks.
