Paid date is set to 1/1/70 0:00

When I export orders from my current shop, the paid date in the .csv file is set to 1/1/70 0:00 on some of the orders.

When I import, this then puts the order history out of date order, with all the 1/1/70 orders at the end, not in the chronological date they were ordered.

I’ve tried exporting without this column, but when I import more than half the orders fail.

Any assistance would be appreciated.
