I have the same problem. The order of the fields seem to change randomly. Unfortunately Tom’s suggestion of setting the names for exporting the CSV does not work for me. If I do that I get empty quote marks (“”) instead of data.
Even if that did work it is not ideal when viewing the data in the backend to have the fields in a different order for each submisssion.
This is unfortunately not the only bug in what could be a very useful plugin. Perhaps the slogan should be changed to “comes with the power of a tank, but drives like a faulty tank!”
