Only in LWC Web Entry, why am I asked to submit Insured Report Number (DN 0026) when it is not required per the Element Requirements Table?

Insured Report Number is a number that is assigned by the Insured or the Web Entry User to be used in identification of the claim. Whoever is creating the report can decide what number to use in that field, but typically our customers use the same number as the Claim Admin Claim Number (DN 0015) to make it easier.
