When reporting a new issue, users can pick a "Product Version" from a dropdown. For Reporters, that dropdown correctly only offers released versions — that part works fine. But when the report is actually submitted, the system rejects it, saying the version is invalid — even though it's a perfectly normal, released version that was legitimately offered in the dropdown.

This only happens for accounts below "Developer" level (the default setting for who's allowed to report against unreleased versions). Administrators and Developers don't see this problem, so it's easy to miss unless you test as a lower-permission user.
