Strange mayan ramp

Tried to make a ramp with the vertices selected as in video but… this is the result:

I’m trying to figure it out…

Section 02, Lecture 29
Edge Loops, Loop Cut and Slide
I did not see the part in the challenge where you asked to create the ramp.
I created both cuts in the center, the first I used 0, the second I used 1 to put it in the same position of the first.
I then moved the current selected cut by .1 and then used ALT + RIGHT-CLICK to select the second cut and moved it by -.1

I then watched the video and put in the ramp. Did I miss the part in the challenge, or was this added after the challenge? Does not really matter, as I got it done.
