Zbrush Alphas tiling

[Zeero]

I have a simple JPEG alpha here (since ZBrush still can’t import PNG files) and I am trying to imprint the logo on the Batman’s chest but even though my Tiling of Alphas is at 1 somehow Zbrush still makes this tiled. Anyone knows why?
thanks

1. zbrush can import png
2. check strokes : modifier : roll and disable it.
3. use the dragrect to drop the alpha on the chest.
