At present, when creating a new company in BC, in order to set up a company that includes all US localizations you must choose the "Production - Setup Data Only" option which inherits the Cronus chart of accounts, posting groups and default journal batch settings, all of which point back to the Cronus GL accounts. Once you delete out the Cronus COA, all of those artifacts are left strewn throughout the system and it is up to you to hunt them all down to clear them out lest they wreak havoc on testing scenarios that inadvertently bump into them.

There should be an option to create a clean production company with all necessary US localizations free of all of those Cronus setup artifacts.
