The  namespace takes its name from the wiki it is on. If your wiki was originally named "Abbys Wiki" (no apostrophe), then all  namespaces will take the form. It is unfortunately something you cannot change. You can contact staff to see if there are any solutions they can provide, but this is how the Mediawiki framework works...
