View full length post on front page

Under general options > read I have selected the option for showing full posts on the first page.

But I’m still getting excerpts instead.
I see no options under customization for dazzling that would give me full texts.

I most click on the headline to see the full posr and I don’t want to. I want to show all posts on one and the same page.

Please advise, and many thanks.
