Possible issue with help documentation

I don't know where to report a possible documentation error. It occurred at this URL.
https://www.gpsoft.com.au/help/opus12/index.html#!Documents/Flat_View.htm

Possible Error: I believe there might be an issue with your documentation. I was a little confused with the IMGP2927.jpg and Argentina_0004.jpg file.

Thanks Bob.

Here's the image to the error. I messed up trying to put into the original message.

It's ok Bob, we've got it. Thanks!
