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 also still missing the Divinity Engine DLC. I bought the game directly through steam on Thursday, release day, basic package, so I have no other DLC which means no DLC tab at all for Divinity OS2. I've also tried, restarting Steam, verifying D:OS2's integrity, and reinstalling, all for naught. It's possible I didn't make the list by purchasing later?
