Slickgrid GetItemMetadata function refers only to the last item

[mpgr04]

I am trying to change the style of several rows with the following code block:

DV.getItemMetadata = function (row)
                {
                    let description = this.getItem(row).Description;

                    if (description != null)
                    {
                        return {
                            cssClasses: 'notify'
                        };
                    }
                    return null;
                }

Here I can see that this is done correctly for all elements, but only the last element is colored.

StackOverflow could not help me here so far
