Querying User custom fields does not seem to work

Hi, I am trying to query for users based on custom define fields but for some reason ACS is not adhering to my where clause in my query statement. For example I have

Cloud.Users.query({ page : 1, per_page : 1000, where : { role : "Employee", store_id : Ti.App.Properties.getString("userStoreId"), deleted : false } });

for some reason it does adhere to the deleted : false property. It returns a user even if deleted is set to true.
