Dynamic title in chart doesn't reflect selected hierarchy level through Drill down

[harry_pbi]

Hi,

I've got these two measures:

DateHierarchySelected = 
SWITCH( TRUE(),
    ISFILTERED('Date dim'[Date]), "Date",
    ISFILTERED('Date dim'[Year Week Name ISO]), "Week",
    ISFILTERED('Date dim'[Month Name Short]), "Month",
    ISFILTERED('Date dim'[Year]), "Year", 
    "Hierarchy not selected"
)

and

DateHierarchySelected2 = 
SWITCH(TRUE(), 
    ISINSCOPE('Date dim'[Date]), "Date",
    ISINSCOPE('Date dim'[Year Week Name ISO]), "Week",
    ISINSCOPE('Date dim'[Month Name Short]), "Month",
    ISINSCOPE('Date dim'[Year]), "Year", 
    "Hierarchy not selected"
)

For dynamic title testing I've got:

DynTitle = "1: " & [DateHierarchySelected] & ", 2: " & [DateHierarchySelected2]

I have each measure in the tooltip of bar chart and I use DynTitle as a title of the chart.

When I use Drill down in the chart, in the tooltip at any bar in the chart each measure shows the correct date hierarchy level, but DynTitle shows different value in the title of the chart, see screenshot below.

Every solution in this forum suggests using formulas I have in my measures, but they dont' work for me, what am I doing wrong?

Thank you for your help.
