Counter increments by two

When using Auto Save and setting filename as , the file name increments by two not one.

1st file saved as 0001
2nd file saved as 0003
3rd file saved as 0005.

I would like the filename saved by increment of one therefore, File1 = 0001, File2=0002, File3=0003, etc

Thank You.

Is there a forwarding to another PDFCreator Printer set up?
That's new to me.
