HLC Colour Model saved as Lab Colour Model

[Darkoni]

Scribus has these Colour Models:

* CMYK
* RGB
* Web Safe RGB
* Lab
* HLC

When colours are defined with HLC Colour Model, they are actually saved as a Lab Colour Model !?!?

Here is how it is saved in Scribus .sla document:

Code Select Expand

<COLOR NAME="ColourLab" SPACE="Lab" L="100" A="0" B="70"/>
<COLOR NAME="ColourHLC" SPACE="Lab" L="70" A="23.9414100327968" B="65.7784834550136"/>

Why is that?
