Selection save into not working in grid field

Question

Hi, I am using a grid field and a rule input to save the selected rows, but all the selected row values are not saved in the rule input. Suppose I am selecting four rows only the value of 2 rows is saved in the rule input. When I select all the rows at once this is a problem. But if I select one row after other it doesn't create a problem.Attaching the code snippet for reference: 
 
 Any help in this regard will be appreciated.

Hi, I don't understand why else condition logic would work according to you. but here is the logic for your requirement, you can optimize it -> selectionSaveInto: {
 ri!selectedItems,
 a!save(
 local!currentSelectedRow,
 fv!selectedRows
 ),
 a!save(
 local!currentDeSelectedRow,
 fv!deselectedRows
 ),
 if(
 contains(
 touniformstring(
 property(
 ri!selectedRow,
 "id",
 ""
 )
 ),
 tostring(
 property(
 local!currentSelectedRow,
 "id",
 ""
 )
 )
 ),
 {},
 {
 a!save(
 ri!selectedRow,
 append(ri!selectedRow, fv!selectedRows)
 )
 }
 ),
 if(
 rule!CPPS_checkIsNull(local!currentDeSelectedRow),
 {},
 a!save(
 ri!selectedRow,
 remove(
 ri!selectedRow,
 wherecontains(
 tostring(
 index(
 local!currentDeSelectedRow,
 "id",
 ""
 )
 ),
 touniformstring(
 index(
 ri!selectedRow,
 "id",
 ""
 )
 )
 )
 )
 )
 ),
 
 },
