On the last master datagrid row, when I click to expand button to show detail datagrid rows, No data shows in grid

On the last master datagrid row, when I click to expand button to show detail datagrid rows, No data shows in grid, See attached pictures of it. However, if I turn the mouse wheel the rows show.

The master datagrid has 970 rows with details rows.

It works great if there is room to expand last few rows to expand the detail datagrid rows show.

I have tried a few things but nothing has worked?

Thanks

Apologies for the delayed response, I’ll investigate this here asap. Can you share a bit of details in the meantime? RAD Studio version, framework?
