Slicer Dropdown not sorting correctly

Hi Anonymous 
Just append 1 2 3 4 in front of your value stream name.

Like below.

I have this data 

I want to sort according my my prefrence.

I have created calculated column.

Sorting = SWITCH(TRUE(),

            WOW[Campaign Type]="SPONSORED_DISPLAY", "1.SPONSORED_DISPLAY",

            WOW[Campaign Type]="SPONSORED_PRODUCT","2.SPONSORED_PRODUCT",

            WOW[Campaign Type]="SPONSORED_BRAND_VIDEO","3.SPONSORED_BRAND_VIDEO",

            WOW[Campaign Type]="SPONSORED_BRANDS","4.SPONSORED_BRANDS"

            )

 

 

 

take you calculated column in slicer. 

 

I hope I answered your question!
