I'm having trouble deleting certain materials from my blendfile.
In the example below you can see that the material appears to have multiple users while in fact there are no other objects in the scene that have this material assigned.
In the material browser the material shows as follow: (however it should be called ''0 old Red Leather'' if no other users have this material assigned if I'm correct)
I've tried unhiding all objects, selecting linked materials by pressing SHIFT+L, saving and reopening the blendfile but none of these methods seem to work.
What else could I do to delete these materials from the blendfile?
