Thank you for contacting Clarizen Support. I tested your file and I was able to successfully import data into my demo instance. The only column that does not come across is "Allow Emails", this is due to NONE license type. If you change the license type to Email license, Allow Emails field should be mapped correctly.
Try the attached file (Copy of Test people import) and let me know how you go with this. If you still encounter problems, please open a case and I will be happy to assist you further.
All the best,
