The normalization gain is the gain factor applied to normalize the
signal level during export.

If you've configured normalization target to be 0dBFS (default) it means
your master peaked at +3.8dBFS  and the export was attenuated so that
the audio does not clip.

As for LUFS, LU, don't forget to follow the link from the forum thread:
http://www.tcelectronic.com/loudness/loudness-explained/  In short it's
average loudness and dynamic range.

Cheers!
