dear mr. watcharapong,
thank you very much for sending the documents to sign.
after opening the files i saw that some of the text is "overwritten" by another letters. for you more easy to found i change the letters to red in both files.
may i ask you to check it and send me please again.
the files are protected files, may be this is the reason for overwritten. may be you can unlock the files or send in pdf format.
thank you again and have a pleasant evening.
nice greetings peter murhammer
