Milford Sound missing from New Zealand Photoreal Scenery ?

I recently downloaded the X-Plane 11 New Zealand Complete Photoreal Scenery (new-zealand-complete-photorealistic-xp11.zip). However, when flying into/out of Milford Sound airport (NZMF) X-Plane 11 appears to be using it's default scenery for this area. 

This is my custom scenery loaded (taken from the log file):

and this is an extract from a later part of the log file:

There's a similar warning later for scenery file -45+166

The three missing scenery files are indeed not listed in the log file of loaded scenery files.

As Milford Sound airport is located -44.6737 south and +167.9242 east it would appear that the tile required is -44+167, which is one of the missing files.

Has anyone else encountered this issue?

I'm new to X-Plane 11, but it seems a straightforward correlation between the warnings in the log file, the missing files in the list of loaded scenery and the physical location of Milford Sound airport.

I'd rather not download the entire zip file again if the result is going to be the same but I just wondered if anyone else has had this same issue?

I would also apologise for the length of this post, but thought it better to give all relevant information upfront, to save time for anyone in a position and kind enough to offer any response.

Thank you
