Visualize XML into PDF throws error if XML contains multiple SpecifiedTradePaymentTerms blocks

[OnnoGabriel]

Mustang 2.14.2 throws an error, if an XML with multiple SpecifiedTradePaymentTerms ("Teilzahlungen") is visualized as a PDF.

These are the SpecifiedTradePaymentTerms blocks in the factur-x.xml:

<ram:SpecifiedTradePaymentTerms>
    <ram:Description>1. Teilzahlung 228.00 EUR fällig am 28.11.2024</ram:Description>
    <ram:DueDateDateTime>
        <udt:DateTimeString format="102">20241128</udt:DateTimeString>
    </ram:DueDateDateTime>
    <ram:PartialPaymentAmount currencyID="EUR">228.00</ram:PartialPaymentAmount>
</ram:SpecifiedTradePaymentTerms>
<ram:SpecifiedTradePaymentTerms>
    <ram:Description>2. Teilzahlung 228.00 EUR fällig am 24.12.2024</ram:Description>
    <ram:DueDateDateTime>
        <udt:DateTimeString format="102">20241224</udt:DateTimeString>
    </ram:DueDateDateTime>
    <ram:PartialPaymentAmount currencyID="EUR">228.00</ram:PartialPaymentAmount>
</ram:SpecifiedTradePaymentTerms>

The whole XML is valid. But if I try to visualize the XML as a PDF with the --action pdf option, Mustang CLI throws an error:

In template uebersicht on line 13 column 35

However, the visualization as a HTML page with --action visualize runs well, it is just the PDF converter.
