CF 25: Team Builder White Border around Vector Images

I am having a problem with my high resolution images I am uploading for logos. They all have a white fuzzy boarder around them when placing them on the field. I have never had this issue until now. These are vectors that I am exporting as PNG's that I made in Adobe Illustrator. It doesn't make any sense to me why the logos are showing up this way on the field. 

Any Help would be much appreciated!
