Field Won't Show in Azure AD B2C Custom Policy - azure-ad-b2c

Question

The following field won't show up on my signin page, why not?
In TrustFrameworkExtensions.xml
<ClaimType Id="extension_AssociateID">
<DisplayName>Associate ID - associateId</DisplayName>
<DataType>string</DataType>
<DefaultPartnerClaimTypes>
<Protocol Name="OAuth2" PartnerClaimType="associateId" />
<Protocol Name="OpenIdConnect" PartnerClaimType="associateId" />
</DefaultPartnerClaimTypes>
<UserInputType>Readonly</UserInputType>
</ClaimType>
I've added it to my TechnicalProfile
...
<InputClaim ClaimTypeReferenceId="extension_AssociateID" />
...
<OutputClaim ClaimTypeReferenceId="extension_AssociateID" Required="true"/>
To debug it, I've added a bunch of variations and they all work.
the label is {id after extension} - {PartnetClaimType}

Answer 1

I threw in the towel and decided to use the associate_id field name even though that was not what I wanted and then associate_id stopped working too. This lead me to the fix.
The fix was to remove it from my OutputClaims in my TechnicalProfile AAD-UserWriteUsingLogonName
<TechnicalProfile Id="AAD-UserWriteUsingLogonName">
<Metadata>
<Item Key="Operation">Write</Item>
<Item Key="RaiseErrorIfClaimsPrincipalAlreadyExists">true</Item>
</Metadata>
<InputClaims>
<InputClaim ClaimTypeReferenceId="signInName" PartnerClaimType="signInNames.userName" Required="true" />
</InputClaims>
<PersistedClaims>
<PersistedClaim ClaimTypeReferenceId="signInName" PartnerClaimType="signInNames.userName" />
<PersistedClaim ClaimTypeReferenceId="email" PartnerClaimType="strongAuthenticationEmailAddress" />
<PersistedClaim ClaimTypeReferenceId="newPassword" PartnerClaimType="password" />
<PersistedClaim ClaimTypeReferenceId="displayName" DefaultValue="DoNotUse" />
<PersistedClaim ClaimTypeReferenceId="extension_associate_id" />
<PersistedClaim ClaimTypeReferenceId="extension_organization_id" />
</PersistedClaims>
<OutputClaims>
<OutputClaim ClaimTypeReferenceId="objectId" />
<OutputClaim ClaimTypeReferenceId="newUser" PartnerClaimType="newClaimsPrincipalCreated" />
<OutputClaim ClaimTypeReferenceId="authenticationSource" DefaultValue="localAccountAuthentication" />
<OutputClaim ClaimTypeReferenceId="userPrincipalName" />
<!-- <OutputClaim ClaimTypeReferenceId="extension_associate_id" /> -->
</OutputClaims>
