By the sounds of it it's to do with the style and colour by layer in the scene. To fix this go to your layers dialogue and select arrow at the top (pictured below) and deselect 'Color By Layer', then make sure the 'Shaded With Textures' style (pictured below) is selected and the texture of the tiles should now be visible. You can also draw the tiled area in Layout if you're just after a hatching.
In regards to the component issue you're having, this is with the development team now and will be included in the next release which should be released in the next couple of weeks.
