RobotStudio event

File contains duplicates

Options
Hi
I am attemting to load the EIO parameter file to Robot Studio 5.13. I select load parameters and replace duplicates. When the file is loading it stops and a message appears saying "File contains Duplicates.  I know the only section I am editing in the EIO file is EIO signal.  My question is there anyway to check for duplicates?  I have gone over the section but I am missing where the duplicates are.

 

Thank you,
