UV Unwrapping help

So im mostly a noob to this. Im wondering how I can remove this selected UV Texture because it seems to be blocking the entire UV map from being edited.

Instead of selecting all the faces and hitting unwrap, try unwrapping different parts of the model at a time. You can do this by selecting only the faces you want. I hope this helps and happy blending.

could you explain in a little more detail?
I’m not clear on what you mean by “blocking”
could it be you’re in a different editing mode than you want to be?
