Problem with getting the Top 5 entries

I've been trying to follow the examples on the forums, but I'm getting the incorrect output when trying to get the Top 5 Entries in my column.

Given the following data:

I would like to get the top 5 results from the table. I tried the following formulas:

[Measure] Violation Ranking = RANKX(ALL(Violation_Data), COUNTA(Violation_Data[Violation]))

[Column] Top Violations = IF([Violation Ranking] > 5, "Others", Violation_Data[Violation])

But I'm still getting all of the results from [Violation] (I think it has something to do with the Calculated Column). I tried using a Visual Filter instead (show only [Violation Ranking] <= 5), but I'm still getting the same results (the [Violation Ranking] of each [Violation] is 1 (which is odd, to say the least) that's why all of the violations are displayed.

Anyone know how to correct the given DAX code?
