Help can't end my patrol

[soldat32]

I have the current TM mod installed and I was tasked with a Photo recon mission.I
managed to sink a good deal of tonnage on the way there.Got into the harbor and snapped a ton of pics (Ships locked on) but could not get the "Mission Complete" no matter what I did.I decided Id had enough after surfacing and sinking said ships in harbor.(There were no destroyers or shore batteries at this small port.) and headed for home.Sunk more tonnage along the way.Now Im back at midway but the "End Patrol" button is blacked out.My only options are to refuel/rearm or postpone.Is there anyway to end this mission and head for my next patrol in this campaign?I really hope so because it was a very sucessful patrol as far as ships sunk and I did get the photos.
