Have you tried moving the Due Date in the import definition to be the last header field set?
Are you setting the Invoice Date or letting the system default it for you?
If the latter, trying making sure to set the invoice date before the terms code, then set the due date.
There is probably another way but if you want to using the current date for the invoice date, set the field to calculated and use coSession'SystemDate$, coSession'ModuleDate$, or DTE(0:"%Y%Mz%Dz"). I seem to recall at one point something like <SystemDate> could be used but i'm not positive about that so i just use one of the above methods.
