Why can’t i find some addons in the kodi repo

Hi!

I can’t for the live of me discover why i can’t find uitzendinggemist and rtlXL addons in my install of Kodi (Latest openelec).
The list on Kodi.tv says it should be there, but it’s not… Sad

Is there an url to the kodi repo, so i can try and instal the kodi repo thru filemanager?

Any help is much appreciated!
