Acrobat 11 - prevent file name changing when adding signature via Fill&Sign?

[johnatbkd]

In Acrobat 11, when adding a signature via the Fill&Sign tool, and then saving the file, the file name has -signed appended to it.  I would like to know if there is a way to retain the original file name.  My organization uses a mixed environment - currently in transition to Acrobat 2017 from Acrobat 11.  Acrobat 2017 does not append the file name, and we would like to have consistent behavior across our environment.  I have looked through the settings and registry and dont see anything that jumps out at me.  Any help is appreciated.
