Level 3 - Accounts show in 8.2.1 can not be found in A1Accounts list

Review Level 3 model build recently and looks some content are refreshed. And in 8.2.1/ 8.2.2 shows stories on modification of account targets. Above sample of accounts are not in A1 Accounts list in Level 3 Model. Are these accounts just sample or somewhere can refresh the A1 list? (I download it from Level 3 course just now but can not find these accounts)
