How can I split a catalog item form into 3 columns evenly?

[Apex Predator]

I have a catalog item with multiple variables.

I have used Container start and container split multiple times to get a view something like this,
But this is uneven with the first column occupying 50% of the form width.
Is there a way I can split these evenly?
I tried setting the variable width(Problem Category) to 25% but it did not change anything. It shows the following message inside the variable.

Hi,

This is as good as it gets. 

If you have 4 columns then you will see it evenly, or with 2. 3 Columns will look the way you already have , no way to get it even.

Hi,

Just checking to see if this is answered or not?

Are you sure we can get an even view in a 4 column layout?
Because I see it is still uneven.
