Hello Guys

Can someone explain this issues to me here, i have been testing some new ads on the site making sure that the listing forums i created are correct but what i found was after i cleared my browser cache the site defaulted back to my location which is fine.

Now what i did notice was the ads that i posted where not showing on the site at all even going through the categories that i posted them in, so what i then done was started to remove the extra locations from the url using the location box on the home page and once i got down to just the url the ads shown up again?

Here are example urls that show the ads below


Here are examples of urls that don't show the ads below


Why has this happened please?
