Cropped images in archive

Hi Enfold team from Spain
I’m developing a new website using Enfold that uses the posts of the old one, and I get the images of archive page cropped instead of redimensioned to fit width space (using author unico, small image), I have the option in media, crop thumbnail images disabled but still the same.. is there any way to show the images resized, not cropped, in this layout?
Thank you very much in advance!
