Sorry to hear of the problem you are having but please note that this is an issue of Unyson plugin that you have used to create those columns.
The Unyson plugin developer will fix it but not sure when so we are just trying to help you to resolve it by developing custom CSS code which may not proper solution.
We can try to fix the major issues like IE issues but other minor issues like spacing issues you have to ignore or fix it yourself or hire developer to fix it or do not use margins in between the columns or just do not use unyson page builder to create columns.
Try using below CSS code to resolve IE issue.
body.home .sh-section-6b60dc9e2043efe53db6b9bfc8f9a97c .fw-row .sh-column.fw-col-xs-12.fw-col-sm-4 {
overflow: hidden;
}
