Scaling billboard material component

We are using a material billboard component within an actor blueprint and we are trying to change the scale of the billboard by changing the values on the base size x and y. When we alter these values the billboard does scale correctly within the editor. When we go to build the application to an IOS device, the billboard goes back to its default scale as if we didn’t it at all. Is this something that could be wrong with the material billboard component or are we missing something obvious?
