Starting with the release of Strategy ONE (March 2024), dossiers are also known as dashboards.
In Strategy Web 2019 and above, when running a dossier with row headers centered in the middle (vertically) of the grid, row headers do not appear correctly as you scroll down. Row headers should appear at the top of the dossier instead of the middle, as it is set in the properties.

The following steps were used to reproduce the issue in the Strategy Tutorial Project.
This issue is being investigated by the Technology team.
