[Fixed]-Override template tag in wagtail cms?

You can customise the buttons for the index page by setting a custom button_helper_class on your ModelAdmin class: http://docs.wagtail.io/en/v1.8.1/reference/contrib/modeladmin/primer.html#modeladmin-button-helper-class

(Incidentally, the tag and template are named result_list, not results_list – perhaps that’s why you weren’t able to override it?)
