Microsoft Report builder YTD Calculation Error

Hi all, 

Ive been struggling with an issue for a long time in Microsoft Report Builder and have not found anything that worked for my model. I have created a very simple dataset to replicate the problem I am having.

I have a powerbi dataset connected to Microsoft Report Builder through dax studio

My data model has 3 columns:

- Region 

- Date 

- Amount

I would like to display a YTD value

If i selected Jan 2023, the YTD measure returns the correct value

If i select Jan 2023 and Feb 2023, the YTD measure returns the correct value

If i select Jan 2023, Feb 2023 and March 2023, the measure returns the correct value

If i select Feb 2023 and March 2023, the measure returns incorrect value - It returns the sum of the periouds in the filter selected. 

I need it to return the YTD for the max date in the filter selected

The dataset and report builder files can be found here 

Any help would be greatly appreciated
