PDF merged document title getting distorted


PFA samples of source, target and merged file. The sample code given for groupdoc is working fine for docx and pdf. but in case of pdf the title is getting distorted. Kindly check and let me know if i need to include any new setting for pdfresult.pdf (90.9 KB)
source.pdf (46.7 KB)
target.pdf (47.6 KB)


Also note if i remove above header and groupdoc log then merging after comparision works fine.
