It wont depend on the archiver Data retention. But the reason for not pruning is, there might be a previous FULL backup which needs the logs to recover the data.
There might be a LOG_RULE applied.
Can you please check the data retention fore cast report and see the reason why these jobs retained?
Also in case you don't need those jobs, please reach out the support and open up TR. We will check and verify.
We need the commserver database to be staged andw we need the range of log backups from which date to which date not required.
So that will help getting support on this.
