Hello,
The watermark numbers [4:0:v7.0] indicates that you are using version 7 of the DynamicPDF Merger product, but have not added a valid license key for v7.
Also, the code sample you shared shows that you are using the DynamicPDF Merger product but are adding a license key for DynamicPDF Rasterizer.
To avoid the watermark on the output PDFs, please make sure to add a valid version 7 license key for DynamicPDF Merger.
Thanks,
