It shouldn't. If PRatio is unchecked, which it should be for anything other then newest ecm stuff, it should be looking to work with Zone Map Boundaries. It should never mention anything about PRatio stuff in the import or export dialogs, unless the PRatio box is checked. I use my software almost everyday, tuning pre-2014 stuff and haven't ever run into this issue yet. Not sure I have any idea where to start other than start flowing the screen shots when it screws up.
