It's not possible to file issues against the published 1.0 version of the specification, since only 0.1 shows up:

This is due to https://github.com/HL7/JIRA-Spec-Artifacts/blob/master/xml/FHIR-cpg.xml being out of date. This file is generated automatically by the IG publisher these days - so need to run a new build and submit the new XML in a PR to the repo above to fix.
