    By reading that, this should be caused by the bidirectional relationship of the two calender tables.

     

    Although this may be be optimal (since I don't know if it is essential for you to keep the relationship between the calender table and water flow monthly)I, I think you can remove the relationship between that two calender tables, and then create another calender table. This should make you having 3 calender tables.

     

    And then use that 2 standalone calender table in your slicers and DAX.

    Please see if that works.
