FortiAnalyzer ADOM not using Storage

Hi,

I've set the Data Policy for my root ADOM to 120 days for Analytic logs. All my Fortigates are in that ADOM. However, when I view the logs, there are only logs available for the last 61 days. It never exceeds 61 days plus a few hours, even though the ADOM root has 40 % of unused storage. The analytic / archive ratio is set to 75 / 25. Do you know what I'm doing wrong? I'd expect it to fill the storage until it's full or the data policy is met but it doesn't do any of that.

I also tried rebuilding the SQL DB. It seemed to be working at first, since logs for analytics reached 61 and 20 hours but after 00:00, it reset itself to 61 days and 0 hours. After the rebuild it freed up some space and ADOM root now even has 55 % of unused storage but is stil not logging according to the policy.

Thanks in advance
