The number of fields in your data file probably falls short of the number LiteRadius is expecting. When you uploaded us_filter.txt, with the default upload profile, there is a one-to-one match between the columns of data in us_filter.txt and the number of defined columns in the upload profile (location_id, name, address_1, address_2, etc.).
If your data file doesn't have at least the same number of fields as us_filter.txt, then LiteRadius won't upload the file.
For example if you have the following data file with one record:
1,Fast Company, 123 Main St., Rochester, NY, 14602, 585-555-5555
Then the upload profile would need to be:
location_id, name, address_1, city, state, postal_code, phone, IGNORE, IGNORE,......, IGNORE
