Scorecard and table discrepancy for average session duration

The average session duration data in the scorecard, where I've set the same 'session default channel' filter, doesn't match the data in the table I created by breaking it down by 'session default groups'. While the scorecard shows 06:00:09, the table shows a value like 58:21:00 for the same session default group. The scorecard value matches the data in GA4, so that one is correct. The aggregation for the average session duration within the table is also shown as 'auto', and I can't change anything there. Furthermore, I tried connecting using a third-party data connection source, but the same discrepancy continues. Do you have any ideas on how I might solve this?
