Favourite map showing random pins

Problems
#1

How is the map function meant to work for your favourites?

I click [Favourites] from the top menu:
https://pvoutput.org/favourite.jsp

I am presented with my 6 favourites listed (one includes my own system). However the map shows 5? Is my system hidden?

I click on the [Name] of one of my favourites:
https://pvoutput.org/favourite.jsp?id=11111&sid=2222

I am then presented with 10 ‘names’. Their locations show as 6XXX however on the map, 10 are in WA and 1 random red pin is in SA?

The systems shown on the map are the same ones shown on the list below.

Some markers may contain more than one site. Click on the markers to reveal all markers. I noticed this when a location specified is limited to a postal code.
