Window Capture capturing every window, not specific window.

[TreatsF]

So I'm trying to capture a game that doesn't have fullscreen built-in, so I can't use Game Capture. So I tried using Window Capture! But the thing is, once I picked my game and selected "Window Title Must Match", but it's still capturing every window? Is this intentional, or is this a bug with my version?
