I am publishing the calendar and tag modules in the right section of my template (JSN Glass) but there seems to be no space between each and one overlaps the other.

Tried to find a way to force some space between K2 modules when published, but could not find how to accomplish this.

Is there a way to avoid this overlaping?

This seems to be a template issue.

You should ask the template developer about module spacing.

Solved it. Thanks anyway.
