The DR Analysis of Tracks / Image don't match, was: "Weirdest Thing Ever" Options

[Tormanoid]

First, let me introduce myself, as I've been lurking around the forum before, but never get registered until now
I'm guess I'm sorry for that. Anyway, this is the matter...

I have a 16-track album in FLAC format and I decided to make a DR analysis of them (like I always do, since I have around 300+ FLAC albums).

Software used:
Foobar2000 1.1.11
Dynamic Range Meter 1.1.1
CUETools 2.1.2a
FLAC: libFLAC 1.2.1 (UTC 2007-09-17)

So, I drag-and-drop the tracks into Foobar playlist, right click over the playlist > Contents > Dynamic Range Meter
At the end, Foobar displayed the following window:



...and the following log:

(the tracks with high DR value are just intros, spoken parts, skits, interludes, etc...)

Then, with the CUE + FLAC tracks, I made a WAV Image using CUE Tools.
After finished, just to check I run a DR analysis again... with very strange results.

After finished, Foobar displayed the following window:

What the heck...

So I run a RG scan. First from the FLACK tracks:


(yes, the album suffer from Loudness War)

...and then another from the WAV Image:



Same loudness. So definitely there's no kind of limiting whatsoever: both sounds and (clearly) are, without a doubt, the same.

Just to be clear, in case some track(s) were repeated or missing during analysis, I did this like four times,... same results.
This actually happened yesterday, so I thought maybe it could something that might get fixed when restaring the PC or something.
I came today and got the same results. Besides, I updated Foobat long ago (weeks, maybe over and month), any problems so far, so it's discarded.
Frankly, it's the first time I have no clue what's going on. I hope you guys can help to find the answer.

Greetings.

This might have something to do with the "Grouping" option of foo_dynamic_range. Try checking all the boxes.
