after effects - interpolation between key frames keep on switching to linear

Hey all! Absolute beginner here! 

I wanted to know how I could change the settings on After Effects of the path between my key-frames. It keeps on giving me straight paths when I want it curved. I already changed my settings and turned off the "Default Spacial Interpolation to Linear", but still, it goes to Linear by default. Any idea what I am dong wrong or what I can change? At the moment I am manually changing the path by right-clicking on each key frame and changing the interpolation by selecting "auto bezier". 

Thank you!
