MORTEVIELLE: Mortevielle Mansion was added thrice by the Launcher but one is duplicated with mass add

[i30817]

This is, i'm 100% sure a bug, and very strange. In short mass adding gave this for this game:

[mortevielle]
platform=pc
gameid=mortevielle
description=Mortville Manor (DOS/English)
language=en
path=/media/i3/Mordred/Games/ScummVM/mortville_manor
engineid=mortevielle
guioptions=sndNoMIDI lang_English

[mortevielle-fr]
platform=pc
gameid=mortevielle
description=Mortville Manor (DOS/French)
language=fr
path=/media/i3/Mordred/Games/ScummVM/mortville_manor
engineid=mortevielle
guioptions=sndNoMIDI lang_French

[mortevielle-fr-1]
platform=pc
gameid=mortevielle
description=Mortville Manor (DOS/French)
language=fr
path=/media/i3/Mordred/Games/ScummVM/mortville_manor
engineid=mortevielle
guioptions=sndNoMIDI lang_French

Some more details, i have a mortevielle_mansion_(amiga) directory with the amiga files, in the expectation that they will be supported sooner or later as the sibling of the directory on those scans, and i don't have the mort.dat in those dirs (it's in the libretro extra as usual). I don't think it should matter, but it's here as extra information.

So the game being added twice for the french language on the DOS version directory is very strange to me. In short, it looks like a legitimate bug.
