In columns settings under design options I add a border colour, style and radius however once I save the column and view the border does not show. Then when I go back into my settings colour and style is reset. Can you pleaase have a look http://signaturefloors.dev.flooradvisor.com.au/
We’ve just tested your site, and added border to a column.
Please, take into account that you have to add the border width, colour, style, radius (optional) to make it display properly.
You can check it on the third Tab of the first Tab module here.
