Unable to copy and paste value for line item with list subset type
I have a list and subset of it.
I create a module, add line item, set its type to the subset list
I notice that i can't copy and paste the value of that line item from one row to another, it can't be done by import action too, but if select it manually, then it is fine.
Is it a known limitation for list subset? or is there any other posibillity that might cause the error?
