Just Migrated to Windows 10 - Need Help with Photo App



I have just purchased a new computer with windows 10 and have transferred all of my photos and videos to the new computer. I can get the facial recognition to work it comes up with 7 or 8 faces with only a few photos each and also I can not get rid of the faced I do not wish to save.

Can someone please tell me how to do this or point me in the right direction.
