You have to do one mission at least for EACH, Granny AND Slackjaw, to make Granny appear in the Flooded District.

And since you said you did not do Gentleman Callers, meaning not taking out the thugs at Granny's  door I suppose, you did not do a mission for Granny yet, as she gives the second mission you can do for her only if you fulfilled the first one.

So that is what keeps you from those achievements.
