Combine chart marker with bar and line data sets

[IsLery]

I'm using Combine chart with 2 data sets - line and bar and want to show markers when any of them is clicked.
However, when I click on the bar I always receive an entry from line data set.

override fun refreshContent(e: Entry?, highlight: Highlight?) {
        if (e is BarEntry) {
           // need to get here 
            }
        } else if (e != null){
            ...
            }
        }
        super.refreshContent(e, highlight)
    } 

Please advise how to trigger receiving bar entry as well?
