What you're witnessing is expected behavior - you can't just arbitrarily
pick a subordinate level & display that level only. The levels are nested
within one another so in order to display any one level the levels it's
nested within have to be displayed as well.
If you have an intended purpose there may be some thoughts to be offered but
you'd need to specify what version of Word as well as what it is that you're
ultimately trying to accomplish.
