There is a problem with the file from PDFBOX-4103. Adobe Reader displays "12", but PDFBox
displays "112".

Luckily, the cause is the pitfall that was solved in that issue. For this, change this code
in PDFRenderer:
{code:java}
    public boolean isGroupEnabled(PDOptionalContentGroup group)
    {
        PDOptionalContentProperties ocProperties = document.getDocumentCatalog().getOCProperties();
        return ocProperties == null || ocProperties.isGroupEnabled(group);
    }
{code}
And in PageDrawer, just pass the group and not the group name to {{isGroupEnabled}}.
