FootPrint Material not showing

Hi Everyone,
Please could somebody advise me on my FootPrint texture which I have animated and corrected in the ThirdPersonBluePrints. My actual footprint texture is now showing as a material even though I have changed the settings to ‘Deffered Decal’ (and also changed this in the rendering section under Project settings). Please see the uploaded image below.
I would be grateful if somebody could help me. As at the moment when the character walks it is just a square texture.
