There can be two possible things:
1. while you were looking at WD output in browser you might have dragged and dropped the column at the last---- so you need to reset the settings in browser.
2. sometimes during the drag and drop in view->table just changes the position in layout not in output, so you need to use the move up and move down by right clicking on the column. just try it once for BUKRS move down and then move up, then check the output.
