Notice how Lease and LeaseRequired are not found to import.

This happened because in the spreadsheet, there is a space after "Lease" and "LeaseRequired"

This entity was created from the excel spreadsheet, so there is inconsistent behavior between creating names for fields on the Entity and Bootstrapping data into an entity. In both cases, the column names should be trimmed, both when creating the entity (which it is) and when mapping columns to field names on the entity during bootstrap.
