Vantage Features Widget – gap on the right, not full row

Hi

I am using Vantage for the first time, usually use Corp.
Whenever I add a features widget, there is always a gap down the right-hand side of the column, so not the full row of features is displayed. So if it is 3 per row, 2 per row is displayed, if 4 per row, 3 per row are shown and so on.

It happens every time on every page, I have been through all theme and page settings and can not find out how to sort it

Can you help please
Thanks
