custom category lay out not working soledad

I am trying to customized the lay out of my posts under categories. When I am chossing the appearance under the soledad theme menu everything works. However once saved nothing changed. The lay out is an ugly one with the title apart and the beginning of the post. why the customization under the theme soledad appearance menu is not working? i have tried every other type of lay out it is the same. (attached screenshots)
