Do you have the SPL meter calibration file loaded, and what SPL meter/mic are you using?

Just checking to make sure the SPL meter calibration file was loaded before you took those sweep measurements. It kinda looks like it wasn't.

You're not. Why do you think you are?

BTW, use the standard graph axis we use here at the Shack which is vertical axis = 45dB-105dB and horizontal axis = 15Hz-200Hz.

I think the question he has is why does the rolloff of the sub not more closely match the rolloff shown in the target line. My initial thought before EQing this sub would be to either raise the sub level/volume and remeasure, or lower the target line some. This will give you some headroom for the cuts needed to then EQ down to the target line.
