I am trying to get the add-on to work for the first time. I am getting a huge error message when updating. There appear to be 2 reoccuring themes. one is:
<?xml version="1.0" ?>
<QBXML>
<QBXMLMsgsRs>
<ItemNonInventoryAddRs statusCode="3100" statusSeverity="Error" statusMessage="The name &quot;GFR220833&quot; of the list element is already in use." />
</QBXMLMsgsRs>
</QBXML>
and the other is:
<?xml version="1.0" ?>
<QBXML>
<QBXMLMsgsRs>
<ItemNonInventoryModRs statusCode="3170" statusSeverity="Error" statusMessage="There was an error when modifying a ItemNonInventory. Cannot use SalesAndPurchaseMod aggregate when the item is not reimbursable. " />
</QBXMLMsgsRs>
</QBXML>
I have over 6000SKUs and it appears that each one generates each of these snippets of error message. Between the snippets there is additional info, but it does not seem be error messages.

The first one appears to be because I already have my products loaded in Quickbooks, but I don't have a clue about the 2nd.
