The runway heading for this airport are reversed in all themes.  I don't know where these are generated so that I can suggest an amendment to the source.  I found it quite difficult to land in reverse 😉  

 

Are you using an addon for LFHM? It appears you may be using MSFS hand-crafted version from world update IV or maybe Bank Angle Studios addon for LFHM.

I am using LLH Creations (http://www.llhinfo.com/lfhm_msfs_en.html) LFHM and runway headings are correct.

If you are not familiar with LLH Creations check them out - I find their airports to have uniquely "real" and appealing qualities. Whether they are accurate I can't attest as I've never been to any of them IRL.

 

This is to 100 percent an issue of an airport add-on or the stock airport. LNM reads the runway numbers directly from the MSFS BGL files or X-Plane apt.dat and does not calculate them.

I suppose this is a stock airport add-on from Microsoft having the path ...\OneStore\microsoft-airport-lfhm-megeve. Unfortunately the Microsoft airports have a lot of such issues.

I'd look for a payware or freeware add-on as Steven suggests above.

Thanks AlexL Stock airport - no add-on.  It's not a 'big' issue know the problem but casual vistors to the airport might puzzled.  The Airport Info Dock shows Runway 33 with the correct  heading of 153 and 333 for Runway 15 - just a typo.
