US Core Provenance Validation Errors

[Torin-Shepard-athena]

Please explain why https://inferno.healthit.gov/validator/ reports the following error for the attached Provenance resource.
Advanced Options
Pick an Implementation Guide to validate against = hl7.fhir.us.core
Select a profile = http://hl7.org/fhir/us/core/StructureDefinition/us-core-provenance

Problem processing expression ($this.agent.who.resolve().is Practitioner or Device) implies exists() in profile http://hl7.org/fhir/us/core/StructureDefinition/us-core-provenance path Provenance.agent[0].onBehalfOf: Error @1, 2: Found Practitioner expecting a ")" on line 1.

Sample_Provenance_for_Condition.txt

This Provenance resource has agent[0].who reference to Practitioner and agent[0].onBehalfOf reference to Organization. Why does inferno online validator report an error with this content?

This is a FHIR registry issue. Inferno validator, and the underlying FHIR validator jar, uses the current published version of an IG. For some unknown reason, validator pulled US Core v3.1.0 as "current version". I already submitted a question to zulip argonaut stream (https://chat.fhir.org/#narrow/stream/179175-argonaut/topic/Java.20validator.20picks.20wrong.20version.3F). Hopefully someone could fix the FHIR IG registry.
