Placemark list not in order

When I first open my map as an article then the place mark list is not listed alphabetically. After I refresh the page it is listed correctly. This is a problem because every time someone opens it for the first time the list seems to be randomly ordered until they refresh the page. Any ideas? I tried to manually order the place marks but I can't seem to edit the order field.

Hi.

May be you define your placemarks by text address. In this case I use geocoder to get latitude and longitude for placemarks, and it is asynchronous executed, and the results come by different time. The second time (refresh) it can be cached and comes in call time without delay on geocoding

You are right thank you that fixed the issue i was having.
