Davinci Resolve Time Curve not behaving as I think it should.

Was watching a youtube video about how to time ramp (don't want to link it unless requested so it doesn't look like I'm advertising), and it doesn't seem to be working as expected.

Basically I'm just experimenting with wild slow downs and speed ups. All I'm doing is opening the time curve, creating two points, then decreasing inbetween the points for a slow down inbetween them. Simple.

Well what's happening is it's affecting the entire playback speed of the whole timeline. Everything slows down. What's the dealio?
