It’s because the graph’s lower axis is set so low. Most residential settings won’t have a noise floor below ~30-35 dB, so there’s no reason to set the graph’s lower limit to 0 dB. Adjust the graph's vertical axis accordingly and it will look normal.

Thanks, I'll check that out later, so many little tick boxes in REW to a novice to learn about!

Hmm...all I can find is the "Set Graph Axis Limit" which deals with hz and spl, can't find any controls for axis?

You're in the right place. dB = SPL. The graph's left-side (vertical) markings are SPL.

Looks like the left window has been altered as well, which is why the response stays level for a while. You can fix that in the Analysis preferences, set it to Hann:
