On the "J" key without the homing bar, the arrow sublegend should be lower on the key to align with the "K" key's arrow sublegend. I understand why the arrow is higher on the homing "J" key (though I feel it should still be lower, and be a part of the homing bar's color), but there is no reason for it on the non-homing key.
I think people who specifically opt to use the non-homing "J" key should not have the aesthetic broken with that floating arrow.
