Tax Calculations from Expense Report

We have configued ebtax and it is working fine.  Our problem is that even though we set a tax code on an expense report type line, when exported into payables it is still using the default and not the tax on the individual expense type.  We have set the flag to use the tax rate for Internet Expenses, added the tax rate to the expense type line in the template but it still uses the default.  Are we missing some setting?  We cannot find anything in the documentation other than what we have set up.  Appreciate any help

Thanks,

Susan
