Importing Tracking order not working

Hi,

First of all thanks for sucha fantastic plugin (whenever I make it to work, im sure it will be)

That being said, Im trying to do an import as a test but although the system does not throw any errors and my CSV file is apparently well formated, it just simply says Import completed, but no changes happen to the order status and no tracking info is added.

Not really sure where to start to look if this does not work. The CSV file contains the following:

Order ID,”Tracking Number”,”Carrier Slug”
LTC-11834,123456789,custom_1586393381

Thanks
kind regards
