XFCE Whisker does not recognize icons set in .directory files

I am on XFCE Arch Linux and on Whiskers menu I want to add two custom menu with subentries. I imported two custom menus from Kali Linux (as .menu files) but the icons specified for the subentries are not applied.

The .menu file that call the two custom menus, Red Team and Blue Team, is /etc/xdg/menus/xfce-applications.menu:

and, for example, if we consider Information Gathering subentry stored in /usr/share/desktop-directories and its .directory file as:

[Desktop Entry]
Name=Information Gathering
Name[fr]=Récupération d'informations
Name[es]=Recopilación de Información
Name[hr]=Prikupljanje Informacija
Name[de]=Informationsbeschaffung
Name[it]=Recupero Informazioni
Name[zh_CN]=信息收集
Name[zh_HK]=信息收集
Name[zh_TW]=信息收集
Type=Directory
Icon=kali-info-gathering-trans

and kali-info-gathering-trans icon is stored in /usr/share/icons/hicolor/scalable/categories/kali-info-gathering-trans.svg. Despite this, submenu entry, like the other ones in this red and blue-applications menu, don't appear. The strange fact is that in GNOME they work. Furthermore, if I try to change icon name or Icon= value to an icon named "blueteam" that is in the same folder of kali-info-gathering-trans.svg" icon (and same pixel size and permission (755), it works. Why XFCE or Whisker is not able to detect the icon of subentries by particular names?

Summarizing:

  • icons like kali-info-gathering-trans.svg that dont appear in Whisker submenus, in GNOME they work well;
  • this issue occurs only on .directory files (tested with submenus in Whisker Tree view mode) and not on .desktop files;
  • it occurs only on Whiskers. In the traditional application menu of XFCE this issue does not occur.

I attach one of the image icon files I have this issue. Please store it in /usr/share/icons/hicolor/scalable/categories/. athena-info-gathering-trans-red.svg

Whisker version:
