Hello, I'm working on the "Import data using the Data Import Wizard" challenge in Trailhead and have encountered a technical issue that I need help with. PROBLEM: The Data Import Wizard won't accept my field mappings for importing contact data.

 "The matching field you chose (Name) is not mapped and is required for an Update and Insert operation. You need to map the required field Contact: Last Name." WHAT I'VE TRIED: 1. Downloaded the CSV file correctly (contacts_to_import.csv) 2. Selected "Accounts and Contacts" as data type 3. Selected "Add new records" import type 4. Tried selecting "Name" as matching field - wizard won't accept it 5. Tried changing to "Last Name" as matching field - same error 6. Attempted multiple times to map LNAME → Contact: Last Name 7. The dropdown shows the field but won't save the mapping 8. Created a new playground and tried again - same issue THE ERROR REPEATS: Even when I select "Contact: Last Name" and click Next, the wizard throws the same error, preventing me from proceeding.   QUESTION: Is this a known bug in the Data Import Wizard? Can you help me complete this challenge or provide a workaround? Thank you for your help!
