Managing Menu choices on the desktop in F21

[Max Pyziur]

Greetings,

After installing F21 on a x64 desktop, I proceeded to also install non-RPM 
software.

For these types of software to appear in the menus, there are *.desktop 
files in the directory:
/usr/share/applications

The software that I installed is OpenJUMP, a java-based GIS package 
somewhat like Quantum-GIS (QGIS Desktop).

In the *.desktop file, there is a line that controls the submenu 
placement; it looks like this:
Categories=Education;Geography;Science;

Howver, in this case OpenJUMP has also become it's own Category.

I would like to eliminate this, but the places that I've looked so far 
(Settings -> Desktop) don't offer control of this.

I'm using Xfce as a desktop; but this phenomenon also appears in MATE, 
Gnome, and Gnome Classic.

Where would I look or what file should I edit?

Much thanks,

Max Pyziur

I would have suggested the desktop file, itself.  Though you can
right-click the top of mate menu (in the task bar) to get an edit
option.  You might want to post the actual desktop file to the list, for
people to see.
