REW Question - Export distortion data as text

[Earfonia]

Hi! I would like to get some help with REW Export distortion data as text.
I've read this help section:

File Menu

But in my case I got weird numbers in the THD (%) column. The value in the THD (%) column in the exported text file is totally different from the THD (%) value in the graph.

Here is an example:

At 31.5 Hz, the THD shown in the graph is 0.033%
Pretty close to the 2nd harmonic which is 0.032%
But the exported text showing weird number in the THD (%) cell that correspond to 31.5 Hz: 0.00000023%

Can anyone help if there is anything wrong in the export procedure or option selection?
Why the THD value in the exported text file is totally different than the value shown in the THD graph?

Thank you!

Ok I found the fix, I have to check the 'Normalize data to fundamental':

Oh nice, but what about people who did not want to normalize? Was the problem more like a bug or that is how math and program works?
