Banner Crashes game

Just downloaded new version of pocket edition. That you can craft banners now. Crafted banner. Tried to change design to the skull in anvil. By changing name to sku. Now every time I click on the banner in my inventory. Try to move it to a chest. It closes the game out. So now I can’t click on it or the game crashes. So I’m basically down a slot in my inventory. In the affects version, it would not let me select version 1.2.
