r - Flexdashboard overlapping windows with vertical layout and tabset columns

Question

I created a flexdashboard with vertical_layout:scroll and I have added tabset columns so that each column has a window which scrolls vertically. On my comuter this works very well. However, on a co-workers computer the first tab window overlaps all other windows. What could be the problem?

The Yaml looks like this:

---
title: "Title"
author: "Name"
date: "`r format(Sys.time(), '%d-%m-%Y')`"
output: 
  flexdashboard::flex_dashboard:
    vertical_layout: scroll
runtime: shiny
