Changing Contour sketch to Fully-defined Sketch

I was wondering if there was a way I can change a contour sketch into a fully defined sketch.

The reason why I ask is because in my previous extruded cut feature, I was using a contour selection. Now that I have my sketch fully defined, I want the extruded cut feature to revert back to using its fully defined sketch boundaries. But each time, it will not revert back and gives me an error of not having a "closed contour".

I personally think it's because the extruded cut feature still wants to use the contour feature. To add on to the problem, the sketch has now been converted into a contour sketch. (The way I know this is because the icon for the sketch has a contour icon.)

Let me know what I should do to fix this issue!

Thanks a bunch in advance.
