If you are uploading transactions that are using Product or Service items, and they don't already exist in your QBO database, SaasAnt will create them for you on upload and map them to your Uncategorized Income or Expense lines.
So, make sure that they exist already, or that they match EXACTLY to what you have set up or you will end up with new ones.
You can fix the mapping after it has uploaded by going into your Gear Icon, Products and Services List to edit.
