slicer custom order

HI, 

I have a slicer and want to order it in a custom way (not necessarily alphabetical). As a result i have followed multiple methods to try and achieve this. 

One of them is described here:

Where i have made another column called 'rank', given it a number (1,2,3,4 based on the order i want), and then i get to the last step where it says i select 'sort column.' This last step does not work for one of the two slicers i tried this on. 

How else can i go about this??
