This item has been identified as an outstanding known issue.
When viewing a large grid on a dashboard or in a module, there can be occasions when the bottom rows of data are hidden. The data is present but not visible when scrolling to the bottom of the grid.
In some cases, this issue can be worked around by changing the browser zoom, switching to a different browser or viewing on a monitor of a different resolution. Alternatively, if any line items use a Style other than the default, changing their style to a different one can cause the dashboard to render the grid correctly.
Furthermore, this issue does not occur for grids in our New User Experience.
If neither of these workarounds are suitable in your use case, please contact Support at email@example.com.
