Assert Warp rotates whole bitmap

[beahaxby]

Total beginner here, just been watching tutorials today and yesterday, now I'm trying to do stuff.

As you can see in the video, when I pull out the different pins to try and warp the bitmap, it rotates the whole thing which is not what I want. Why is this happening and how can I stop it?
