Control adds selected values as a new list item

Example: list items are: A, B, C, D
Select A and B
Save the work item.
Select D
Now the list items items are A, B, A;B, C, D
Why is "A;B" getting added to the list?. If this value is selected, then it duplicates the values, so there would be 2 "A"s and 2 "B"s
