"restrict number of columns displayed" -> 1
If you set the number of columns to two (or three) does that take care of the issue?

With two columns not really.
The second column uses up some of the space, but there still is empty space on the right. It's as the columns are left aligned.
With three columns the space is used at its fullest, but the title names are cropped, as I would expect (Like this -> This is a titl...)
