I am having trouble Importing a new set of subscribers from an Infusionsoft export file. I already imported the main file and that went ok. When I try to add subscribers from a subset file which contains only about 50 records, 7 if which are not in the main file, nothing gets added. I am a little confused about the "include these subscribers" requirement on the import form. I put in the tags I want these new 7 subscribers to have, not tags they already have. What could I be doing wrong?
