When configuring a Job, Copy Artifact plugin shows "QA Build" by default" even if we change this to other values.
I've checked on the job config.xml and the setting is correct.

1- Changing value to Release Candidate:

2- Open job config figures invalid info

3- Config.xml file shows correct info:

<hudson.plugins.copyartifact.CopyArtifact plugin="copyartifact@1.35.2">
[...]
<selector class="hudson.plugins.promoted_builds_simple.PromotedBuildSelector" plugin="promoted-builds-simple@1.9">
<level>3</level>
</selector>
