What you expected to happen:

According to this link for Openstack:
https://releases.openstack.org/teams/nova.html
There is a change in version convention from Liberty release until to today.

Old Serie:

Kilo release series is
2015.1.4
2015.1.3
2015.1.2
2015.1.1
2015.1.0

New version convention:

From Liberty release series to today
12.0.6
12.0.5
12.0.4
:

The release that is reported for this issue is Victoria version 22.2.2.:
( 9 release more recent than Liberty series)
22.4.0
22.3.0
22.2.2 <---
22.2.1
:

Conclusion:
Due to the change of version from Liberty release series, the tool is not really taking account of the change.
If it takes only reference from from NVD or GitHub, I believe it is wrong in this case.
