[GNC] CSV matching produces duplicates?

[flywire]

Yes, there would be no matching decisions if it was coded in the input file
but you won't be powering through it, GnuCash still requires user to verify
each [iirc] account (which is coded in the input file). I'm suggesting user
should be able to turn that checking off (since input file has been
checked) and during the input process GnuCash could tag any records it has
issues with.
