   Scenario Outline: Exon reduction
 
+  Exon reductions will expand 2 field alleles to W level before generating
+  exon level reductions.
+
     Given the typing is <Allele>
     When expanding at the <Level> level
     Then the expanded allele is found to be <Expanded Alleles>
     Examples:
-      | Allele        | Level | Expanded Alleles |
-      | DRB1*11:01    | exon  | DRB1*11:01       |
