Images Cropped in lieu of resized

Thumbnail images are showing cropped in lieu of resized.
Solutions already attempted:
Turning off check box in settings/media to crop thumbnail
Adjusted theme functions.php as follows:
add_image_size(‘newsphere-slider-full’, 1280, 720, false); // width, height, crop
add_image_size(‘newsphere-featured’, 1280, 0, false ); // width, height, crop
add_image_size(‘newsphere-medium’, 1280, 380, false); // width, height, crop
