Querying CCQ values ​​via SNMP is not possible with nv2 connections

Hello everyone,
We operate several Mikrotik links here and have switched from nstream to nv2 to improve quality.
Since then, querying the CCQ values ​​via SNMP is no longer possible.
For an nstream link, the following entry appears when querying:
iso.3.6.1.4.1.14988.1.1.1.3.1.10.3 = Counter32: 99
For nv2, it says
iso.3.6.1.4.1.14988.1.1.1.3.1.10.3 = Counter32: 0

Is this a bug and can it be fixed?
Greetings from Berlin!
