Assigning case role to contact in webform- not updating as expected
Rephrased my search and found this question
What determines the suite of Case Roles presented for assignment on the CIVICRM Webform Case Tab?

1st answer talks about relationship names/labels not matching

Newer version of create relationship only allows user to set relationship label. name is auto generated

In this case "Other Professional is". The relationship was assigned the name "Other_Professional_is"

Editting the relationship name  to "Other Professional is", meant that it showed in the case roles.

Don't know if this level of tinkering will have knock on effects anywhere else.
