Issue with Editable Grid

Hi,

I am having editable grid with selection enabled where as the data will be populated based on the selection value in the milestone field.

In which we need to include one of the column as required whenever the selection is enabled.For that I have included the below code snippet in the gridrowlayout.

a!textField(
value: fv!item.item,
saveInto: fv!item.item,
required: if(
contains(
tointeger(
local!selectedIndex
),
tointeger(
fv!item.id
)
),
true(),
false()
),

)

After including the above code, whenever the first row item of first milestone is selected,first item of all the remaining milestone field is  also getting selected.If we remove the above highlighted snippet it is working fine.Also this is happening in Appian 19.2 and 19.3 version.It is working in 19.4.Did anyone face similar issue?Can anyone please help me on this.

Attaching the full source code here.
