While creating a new "Layout Style", if you try to delete it you end up with a bunch of empty unresponsive windows. To fix this you have to restart and delete the file in "FFXIVMinion>GUI>UI_Styles>Whatever you named it" and start over.
I notice when you Save, it doesn't add the ".lua", could that be the issue?
