Hi nvanzyl24 ,

You can create a measure as below base on the measure [3M] and put this new measure onto the visual to replace the measure [3M]:

Measure =
VAR _maxdate =
    MAXX ( FILTER ( ALLSELECTED ( 'Table' ), [Total] <> BLANK () ), 'Table'[Date] )
RETURN
    IF ( SELECTEDVALUE ( 'Date'[Date] ) <= _maxdate, [3M], BLANK () )

If the above one can't help you, could you please provide some raw data in your table (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution. You can refer the following links to share the required info:

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
