QB Issue Resolution:
First see if it actually was. Using account numbers is not a default and is a preference that must be turned on. Go into your company settings from the gear icon and turn on the feature – your numbers might magically appear – if not, with feature turned on repeat the import of the COA but what might happen although is that you end up with a double set of accounts, those with and those without numbers. If you have over 125 accounts your import would then fail as it would put you over the usage limit of 250.
Alternatives – manually edit and add all your account numbers – unless you are on Advanced it will be less than 250 entries at maybe 30 seconds each once you get the hang of it.
Or delete all accounts, make sure the account number feature is turned on and reimport.
