Creating large profile 24x48 tile in Chief Tile Builder

[Elliot]

I am working with the Chief Tile Builder trying to create a matte Black 24x48 tile. I use a lot of larger profile tile like this.  I have watched the video on the Chief Website, and read the reference manual.  I have played around with the settings and cannot make it go 24x48.  I have the tile set as 2:1 Large Profile and the material size under map settings as 24x48 but it doesn't generate a large profile tile.  I cannot find anywhere else to set the size of the actual tile.  Or does Chief not let me use  a large profile tile that large?   What am I doing wrong?
