It didn't need to be fixed. The (k) is in parenthesis so he meant both the k and non-k for the sling adapter.I fixed that for you. However, in the OP's case, it sounds like that did not happen. Dish still sent the wrong 722. (non-k)
As far as the OP goes, he hasn't been back since his initial post so who knows if anything we are saying here is falling on deaf ears.
