I'm importing a csv of issues using the "External System Import" in the Admin console.
I have a column called "Sent?" which has values of "Yes" and "No".
When I import I have mapped these values to my custom field "Sent?". I have mapped "Yes" to "Yes" and "No" to "No".
There are no errors in the import log.
However, when I import, the data is lost and the custom field "Sent?" only has the value of "None".
