align text to the left

Hi,

I would like to change the position of the content (headline, text, button) on the slider to the bottom left. I cant. I tried all options but still sitting in the center. When I do on paragraph and heading align to left I can see in the editor is in the left but when I refresh live site it’s still sitting in middle. see here: https://www.screencast.com/t/vwMlYbvV

Can somebody help me please? Thanks.
