Dive Site Problem: nearby sites

[Willem Ferguson]

I want to make some changes to the user manual pertaining to the 
management of coordinates. So I create an hypothetical dive as follows:

Create a new dive:  Log -> Add dive
Specify a location that I have dived on several occasions. (In my case 
Aliwal Shoal: Cathedral)
Image 'Divesite1.png', attached, appears.
Now I am assuming that I am diving a different part of the Cathedral, 
NOT represented by any existing coordinates. So I doubleclick the 
highlighted option in Divesite1.png.
I hit the button "Apply changes". Now the dive information has been saved.
Then I hit the globe button to the right of the Location text box. I 
want to provide the coordinates.
Image Divesite2.png, attached appears.
But in the bottom list box there are no other locations of Aliwal Shoal: 
Cathedral

I would have expected all my previous dive locations at the Cathedral to 
be listed here.

Typing the coordinates of the new dive site at this stage does not make 
a difference. Neither using the existing coordinates for Cathedral, nor 
by changing the coordinates very slightly to refer to a site not exactly 
similar to any of the existing dives at Cathedral.

Am I misunderstanding the UI?

Kind regards,
willem
