As others have pointed out in earlier posts, MX11 is an entry point for mid-career entrants. Hence, MX11 officers are more expendable as compared to the other ranks because they can be easily replaced. For MX13(I), the organisation knows that it is a "retirement rank" for junior officers so there is no danger of them leaving despite how poorly remunerated they are.
From an organisational standpoint, it is not prudent to give a any increment to these 2 ranks given the limited value it will bring (one being easily replaceable, the other lacking option outside civil service and wont leave). In my opinion, a token 5% is given to these ranks only to support the narrative of a "civil service wide pay revision in order to match the private sector".
