      The source does NOT have tailing spaces, the target has. I added a "X" at the last postion to visualize in the screenshot

      Expected Results

      the collection names are identical source to target when we dump/restore on db level

      Actual Results

      The target collection names (all) got a tailing extra space " " added to the name
