Dormer and Fascia

[ddelaney.wit750576]

Hey all, wondering if someone can help me with a little problem. Hopefully the image link below attaches. I created two dormer windows, attached their roofs to the main roof and cut the cavity out of the main roof to bring up the dormer walls. All is fine until I go to attach fascia boards to the dormer roof. Instead of following the shorter line at the base of the dormer the fascia extends to the length of the dormer ridge and into the bedroom. If I try to pull the length of the fascia back it snaps back the ridge length, very irritating. Is there any way I can cut the face of the fascia to stop flush with the main roof?

Cheers for any feedback
