CDC cleanup job -- history

On SQL Server 2019, I enabled CDC on some tables about 2 days ago. The CDC cleanup job is scheduled to run every day and the retention period is 3 days. When I checked the job history of the cleanup job, I found nothing there. I ran the job manually and by the next day I found that even the manual job I ran was no longer there. How can I be sure that the cleanup job is running as it should, also could there be anything that is clearing the job history? The database is also part of always-on availability group. Please, help.
