gutters not working?

Using Maskitto versions 2.0.1

Great theme! Thank you for providing it for the community.

I am trying to add space between the columns in the Row Layout dialogue box but it doesn’t seem to work. I end up having to add padding to the individual widgets which is not ideal,

Here is a good example of what I mean. https://j2studio.com/millennial1/mortgage-calculator/

I have 20px specified in the Row Styles dialogue yet there is not space.

Can you advise?

Thanks!
