Weka does not discretize last column

I am using Weka to discretize data, but the problem is that it does not discretize last column. Also supervised.Discretize is inactive. Is it a problem with dataset?

The dataset:

@relation R_data_frame

@attribute V44 numeric
@attribute V178 numeric
@attribute V280 numeric

@data
0,3.7,8
0,17.6,6
0,14.2,10
...some more data

Complete data set: https://pastebin.com/raw/RmQ2pD3W

Supervised attribute discretization requires that the class variable is categorical. Yours is numeric, so it is not an option. However you can get this to work with supervised discretization. First select 

filters -> unsupervised -> attribute -> Discretize

Weka Window 1

Next click on the text box that says Discretize (next to the button that says Choose) to set the options for discretization. One of the options is Ignore Class. By default, that is False. Change it to be True.

Changing options for Discretize

Now run the filter by clicking Apply and it will discretize all three variables.
