Quickbooks CustomerQuery with Iterator returning duplicate records - intuit-partner-platform

Question

I have a strange issue, and I am not sure where the error is
I am working on C#, and while running a query with filters against the Customer object, I get a strange series of results
If the filter I set should return 8 records, then my implementation returns 8, 8, 3, 1, 1, 1 records (in that order, in every subsequent call, and all those are duplicate)...
This is how I implemented the Iterator
var customerQuery = new CustomerQuery()
{
ChunkSize = "8",
Item = Guid.NewGuid().ToString("N"),
IncludeFinancialIndicator = false,
IncludeFinancialIndicatorSpecified = true,
MinimumBalanceSpecified = true,
MinimumBalance = 92,
SynchronizedFilterSpecified = true,
SynchronizedFilter = SynchronizedFilterEnumType.Synchronized,
};
var results = new List<Customer>();
int count;
//Loop until find all the results.
do
{
IEnumerable<Customer> partialResult = customerQuery.ExecuteQuery<Customer>(context);
count = partialResult.Count();
//First pass here returns 8 records
//Second pass returns same 8 records again
//third pass returns 3 records
//Three more passes with 1 record each
results.AddRange(partialResult);
} while (count > 0);
Am I doing something wrong or missing anything?
Thanks!
Edit:
this is the code implementing the Paging option....
var customerSet = new List<Customer>();
List<Customer> customerQueryResult = null;
int startPage = 1;
var qbdCustomerQuery = new CustomerQuery();
do
{
qbdCustomerQuery.ChunkSize = "10";
qbdCustomerQuery.MinimumBalanceSpecified = true;
qbdCustomerQuery.MinimumBalance = 92;
qbdCustomerQuery.ItemElementName = ItemChoiceType4.StartPage;
qbdCustomerQuery.Item = startPage.ToString();
customerQueryResult = qbdCustomerQuery.ExecuteQuery<Customer>(context).ToList();
if (customerQueryResult.Count > 0) { customerSet.AddRange(customerQueryResult); }
startPage++;
} while (customerQueryResult.Count > 0);
If I set ChunkSize to "100" I get the 8 expected records, but when trying to run it with ChunkSize = "10" I get 8,8,1 (duplicate records)
