GD Map categories issue

When making changes to listings, the GD map front-end category marker changes to default and no longer recognise the category I assigned, even though it still says it’s in the category assigned back-end.

I have to go back into place quick edit, save it into another category, then quick edit again, and assign it back to the category I want. It will then display on the GD map in the correct category.

I’ve also noticed that the GD map is not displaying a marker for the feature listing, when I upgrade the listing back end.
