Please find the below screenshots
If I select header checkbox(select all), only first five rows are selected
Remainig rows are not selected
If I select row 2 and row 3 and click on add I got wrong output(refer last screenshot)
row 2 and row 4 are added in list2 (but correct output is row 2 and row 3 should be added) after clicking on add all the checkboxes should be unchecked.
Please help me thanks in advance.
