Elementary slack alerts not displaying descriptions

[SimgeChetin]

Hello Elementary team
We’re using Elementary’s Slack alerts feature to notify our business stakeholders about data warnings.
Sending warning notifications to a specific Slack channel works as expected, except that the description field is not displaying.
According to the documentation, descriptions should be included in the alerts, but they are not appearing in the Slack messages (please see the first screenshot I’ve attached).
I’ve added the description in the .yml file exactly as outlined in your documentation, and I can confirm that the description is present in the elementary.dbt_tests table (see the third screenshot).
I’ve also attached the CLI command I’m running on my side.
Could you let me know if this issue with descriptions not displaying in alerts is a known problem? If not, would you be able to help us troubleshoot?
Thank you!
