whereNotContainedIn is not working properly.

This would also be my code, but have a look at this.

ParseQuery<ParseObject> queryLeagues2 = ParseQuery.getQuery("Leagues");
queryLeagues2.fromLocalDatastore();
queryLeagues2.findInBackground(new FindCallback<ParseObject>() {
    @Override
    public void done(List<ParseObject> objects, ParseException e) {
        for (int i = 0; i < objects.size(); i++){
            queryLeaguesObjectsList.add(objects.get(i).getString("leagueID"));
        }
        LinkedHashSet<String> lhs = new LinkedHashSet<String>();
        lhs.addAll(queryLeaguesObjectsList);
        // Removing ArrayList elements
        queryLeaguesObjectsList.clear();
        // Adding LinkedHashSet elements to the ArrayList
        queryLeaguesObjectsList.addAll(lhs);
    }
});

For this query, I am going through the Leagues table and pulled out the League ID, throwing it through a hashes to remove a dup. The queryLeaguesObjectsList is a List

After that, I run this query.

ParseQuery<ParseObject> queryLeagues = ParseQuery.getQuery("Leagues");
        //queryLeagues.fromLocalDatastore();
        queryLeagues.whereNotContainedIn("leagueID", Arrays.asList(queryLeaguesObjectsList));
        queryLeagues.findInBackground(new FindCallback<ParseObject>() {
            @Override
            public void done(final List<ParseObject> queryLeaguesObjects, ParseException e) {
                if (e == null) {

                    if (queryLeaguesObjects.size() == 0) {
                        MethodContants.showLog(TAG, "No leagues to join", true);
                        progressBarContainer.setVisibility(View.GONE);
                        noLeaguesToJoin.setVisibility(View.VISIBLE);
                    } else {
                        ListViewAdapterLeagues adapter = new ListViewAdapterLeagues(listView.getContext(), queryLeaguesObjects);
                        listView.setAdapter(adapter);
                    }

                    if (!ListViewAdapterLeagues.getLoading()) {
                        Handler handler = new Handler();
                        handler.postDelayed(new Runnable(){
                            @Override
                            public void run(){
                                progressBarContainer.setVisibility(View.GONE);
                                viewContainer.setVisibility(View.VISIBLE);
                            }
                        }, 750);
                    }

                } else {
                    Toast.makeText(getContext(), "Error: " + e.getMessage(), Toast.LENGTH_SHORT).show();
                    MethodContants.showLog(TAG, "Error with league in browse. " + e.getMessage(), true);
                }
            }
        });

All of the items are in my list view still. Even the duplicates of leagueID

Ill include some screen shots. The first one is my Leagues table. As you can see, there are four in there, and four are still in my list. I only want the leagues that I DO NOT belong to in the list and to remove the duplicate.
