issue with featured image and Autoblog

Hi, i tried to import the featured images of the posts that im importing but it doesnt work, it isnt getting the first image of the post (i use excerpt import).
And at the same time i have this bug, if i already had selected an image (same image for all posts) i cant delete it, if i click on "Delete" it shows that blank square and thats it, it wont import any image at all.
Wordpress 4.1.2
Autoblog 4.1
