Runway alignment on Map Display

While on the approach to Manchester EGCC I was following the QDM to RWY 24R which is 235 degs and the runway was perfectly aligned out of the window but on the cockpit map display the runway graphic was approximately 10 degs out. With the extended dotted center line it looked like I was landing from the side slightly. All other airfield runways appear ok. Can someone please tell me where I can check the file for the correct runway alignment for EGCC. I have installed the latest AIRAC 0411 update.Many thanksGlen Coyne
