Hello all - I'm trying to use containsAll() but it is returning false (bullet point 3). Below is a pic of the debug log which shows the states from the set. Any help would be greatly apprceciated. 

1. I'm retrieving field values from a text area field called 'States' on a custom setting object and adding the states to a Set. (the custom settings is a list)

        //Get states from custom settings field and add to set
        Set<String> gwStates = new Set<String>();
        
        for(GW_States__c gwSts : GW_States__c.getAll().values()){
            if(gwSts.States__c != null){
                gwStates.add(gwSts.States__c);
            }
        }
        
        System.debug('States in Set ' +gwStates);

2. Then I query a custom object called Association and add the Association's state to a set and a map. 

        //map/set of states from association
        Map<Id, String> assocState = new Map<Id, String>();
        Set<String> stateSet = new Set<String>();
        
        if(assoc.size() > 0 ){
            for(Association__c associt : assoc){
            assocState.put(associt.Id, associt.Association_State_Province__c);
            stateSet.add(associt.Association_State_Province__c);
            }
        }

            System.debug('State in set from association ' + stateSet);
            System.debug('State in map ' +assocState);

3. Now I'm checking to see if the Association state is contained in the gwStates set and the map. Both return false. (see debug log)

//Use compare method to check for matching states
                Boolean state = gwStates.contains(assocState.get(assocEvent.WhatId));
                Boolean statezSetcompare = gwStates.containsAll(stateSet);
                    system.debug('state compare from map = ' +state);
                system.debug('state compare from Assoc set = ' +statezSetcompare);
