Why is Microsoft Dynamics GP getting multiple distribution lines when creating a sales invoice? - microsoft-dynamics

Question

I’m using Microsoft Dynamics GP. First of all, I am a programmer by job title. I have no training and only limited usage on using the Dyanmics GP product. I wrote a program that uses the GP Web Services to create a sales invoice. The sales invoice includes 2 distribution lines. However, when the accountants look at GP, they see 4 distribution lines; each of the lines my program adds has been duplicated. What am I doing wrong? Any other ideas on why this is happening?
Here’s the code for adding the distribution lines (GL codes have been hidden for privacy issues):
//Adds the Distributions - where it hits the GL Accounts
salesInvoice.Distributions = new SalesDistribution[2];
SalesDistribution apSalesDistribution = new SalesDistribution();
apSalesDistribution.GLAccountKey = new GLAccountNumberKey() { Id = "xx-xx-xxxx" };
apSalesDistribution.CreditAmount = new MoneyAmount() { Currency = "USD", Value = itemsReceived.CostEach };
apSalesDistribution.DistributionTypeKey = new DistributionTypeKey() { Id = 1 };
salesInvoice.Distributions[0] = apSalesDistribution;
SalesDistribution salesDistribution = new SalesDistribution();
salesDistribution.GLAccountKey = new GLAccountNumberKey() { Id = "yy-yy-yyyy" };
salesDistribution.DebitAmount = new MoneyAmount() { Currency = "USD", Value = itemsReceived.CostEach };
salesDistribution.DistributionTypeKey = new DistributionTypeKey() { Id = 2};
salesInvoice.Distributions[1] = salesDistribution;
On this page, there should be 2 lines based on the code above, but there are 4 lines:
Here’s the full code for creating the sales invoice (again, identifying information has been removed):
