PLease help sub menu wallpapers keep changing

[size=large]Backgrounds keep changing within submenu….Frown

Hi there using Kodi 16.1 Jarvis with Aeon Nox and having problems with background skins changing.
I have basically made myself the following headings on my main menu.
Sports,Movies,Tv,Radio,Kids Cartoons.
Within each of these headings i have successful made individual wallpapers for each section which scroll from one to another perfectly.
I have now managed my sub menu as required.
For instance main menu says RADIO then sub menu has the following Jango,UK Turks Radio,Ares LIve Radio,T.A Streams.
What i am trying to achieve is a seperate wallpaper for each sub menu item.
So first i say open Jango then via view options top left,click background,then fallback,select set single image background,find in my c drive pictures,chose pic and it saves as wallpaper,then repeat process for new sub menu items.

Whats happening is even if i chose different wallpapers for each sub menu item even though it changes them if i say go back to Jango it has now changed it to match one of my other submenu items.
What happens also is that it sometimes say changes aradio pic in Jango and puts it in a movies sub menu in different section altogether.

I cannot achieve having 1 different wallpaper in every individual submenu item in all sections.
I have chosen 1920×1080 to match my tv picture layout and are using jpegs and png.

Can someone please explain what is going wrong as i have tried several times but still duplicate wall papers appearing.HuhHuh
Thanks for any help given…

Cheers
