When setting your field mappings you will notice that Credit Score, Credit Limit, International Score and Credit Description don’t appear on the list of Creditsafe Fields. The reason for this is because when you install the package, we automatically create these fields for you. They can then be added to a page layout. This can be done using the following steps and editing the relevant page layout:

Setup > Object Manager > Account > Page Layouts 

Alternatively, adding the Company Match Component to your Account Page Layout will also display those fields.
