Help With Straight Table and List box filtering: Multiple filter not working for straight table

[#1]

I have a listbox with LED Checkbox Values "A and B". I have created a straight table which gets filtered as per the selection in Listbox.

For instance :

On selection of A the Straight Table displays 5 rows
On selection of B the Straight Table displays 2 rows

However on  on selection of both A and B the straight table displays 5 rows instead of 7 rows. The top 2 rows are displayed blank.

I believe the straight table is overwriting the the rows of the 2nd selection (Say "B")

Thanks in Advance for you Suggestions

I think it would be helpful if you loaded images of your model (Table Viewer) and Straight Table, and also detail of expression used in that table.

Thanks !!!    I have sorted the issue. There was a problem in dimension.
