Final client status by grouping on selected date range

Hi,

I am fairly new Power BI user, currently working on interesting piece of DAX logic, which should not cause too much hasle, but I feel like I missing something in my code and cannot find out what exactly.

I have data on client movement through different sales stages which structured like this:

I have to represent this data by slowing the max status the client has achieved for any selected date range. E.g. if I select 12.02 to 12.03, I would want the matrix table to add a count to Registration counter like this:

 
Here is the current code that I tried using:

Measure :=
COUNTROWS (
    FILTER (
        'Raw LH',
        GROUPBY (
            FILTER (
                ADDCOLUMNS (
                    SUMMARIZE (
                        CALCULATETABLE (
                            'Raw LH',
                            FILTER ( DateTable, DateTable[Date] >= MIN ( DateTable[Date] ) ),
                            FILTER ( DateTable, DateTable[Date] <= MAX ( DateTable[Date] ) )
                        ),
                        'Raw LH'[LeadId],
                        'Raw LH'[NewStatus],
                        'Raw LH'[CreatedDateTime],
                        'Raw LH'[Id]
                    ),
                    "MaxDate", CALCULATE (
                        MAX ( 'Raw LH'[CreatedDateTIme] ),
                        FILTER ( 'Raw LH', 'Raw LH'[LeadId] = EARLIER ( 'Raw LH'[LeadId] ) )
                    )
                ),
                'Raw LH'[CreatedDateTIme] = [MaxDate]
            ),
            'Raw LH'[Id]
        )
    )
)

In this code, If I understand correctly, I am selecting the data for the selected range, then grouping on the basis of LeadId, interaction Id, InteractionTime and the newStatus. I am also adding another column for the max date. I then select only the rows with max date, and group again by unique event identifier (Id).

As much as I have tested this code, the relative date filtering seems to be working, so does grouping and selecting the latest, thus the maximum, interaction, however when run this measure in the matrix table, it adds count for all interactions during the select time period.

I hope this makes sense and I would greatly appreciate if you could help me with this. I feel like I am so close to getting it right, but as much as try I can't crack this.

Thanks,
Arturs.
