Description of the problem: Expected behaviour & Actual behaviour

As you will know the new "desktop" files, for the translation of their directives they make use of X-Ubuntu-Gettext-Domain. That is, before when you wanted to translate the name of the application indicated in the "desktop" file, the following was done (for example, in ubuntu 14.04):

Name = Printers
Name[es] = Printers
Name[de] = Drucker
...

Currently, many "desktop" files already make use of X-Ubuntu-Gettext-Domain for this, avoiding having to put countless translations in the same "desktop" file. The use of X-Ubuntu-Gettext-Domain is perfectly recognized by the system itself updating its menus to the local language, as I show in the images attached, but desktop launcher programs such as synapse, ulauncher or albert do not detect these translations correctly .

more /usr/share/applications/system-config-printer.desktop 
[Desktop Entry]
Name=Printers
GenericName=Printers
X-GNOME-FullName=Printers
Comment=Configure printers
Exec=system-config-printer
Terminal=false
Type=Application
Icon=printer
StartupNotify=true
NotShowIn=KDE;GNOME;
X-Ubuntu-Gettext-Domain=system-config-printer
Categories=GNOME;GTK;Settings;HardwareSettings;X-GNOME-Settings-Panel;X-Unity-Settings-Panel;System;Printing;
X-GNOME-Settings-Panel=printing
X-Unity-Settings-Panel=printing
Keywords=Printer;Queue;Print;Paper;Ink;Toner;
X-Desktop-File-Install-Version=0.23

Would you know how to solve the problem? Do you know why it is? The truth is that we have tested several desktop launcher programs and not one works correctly. I ask you because albert is perhaps the best alternative to the heavy desktop launcher that includes gnome, mate or kde.

As can be seen in the following images, the system translates perfectly printers into impresoras (LANG=es_ES) in their menus, but using albert it is not possible to find it using impresoras and only as printers. What happens with the desktop associated with printers occurs with many others: disks, system tools, etc.

Thank you very much in advance. I await your response. Regards.
