ICP Amount in Tax Report is double

[PaulTammes]

In Module 10n_nl_tax_statement i make a report for a quarter, and all values look correct apart from the ICP transactions (3b, leveringen naar landen binnen de EU) where the amiunt is double that of the list you see when clicking on the PLUS token next to it.
