Consider a rule r followed by a contraction:

  A, A :- B
------------r
  A, A :- B'
------------c:l
   A :- B'

If you now activate both "Hide structural rules" and "Hide sequent contexts", you will see

    :- B
----------r
  A :-

which is pretty nonsensical, but follows directly from the definition of the two options.
