Data scraping returns (null) values for cells that are not shown on screen

Hello everybody,

i use the data scraping function to collect data from a table in an application (MS Navision).

This works well for the cells which are visible on screen, but the cells that are not visible (without scrolling down) are not seen correctly. In the output it will show all cells outside of the screen with a value of (null).
Se the attached image. From 24 the cells are not visible anymore without scrolling.

I have tried selecting different cells to indicate the datascraping area, but it did not help.
Is there anything else that can be done to make sure UIpath sees the correct data for all the cells?
