Dynamic TopN Selection problem while selecting another filter slicer?

Question

In Power BI, I have created a dynamic TopN visual where we can see top 3 to top 10 teams in terms of total goals scored in FIFA World Cups. I am using a parameter called Top Rankings for TopN selection. However, the TopN selection does not work when I am selecting another slicer Year. When I am selecting the year slicer, the visual shows close to 10 teams although I have selected only 4 teams in the slicer parameter. I am providing the dax measure, table which is used to create the measure and the visual as well.

Dax -

# TopN Teams by Goal Scored = 
VAR ranking = RANKX(ALLSELECTED(All_WC_matches[Teams]), [Overall Scored],,DESC,Dense)
Return
IF(
    ranking <= 'Top Rankings'[Top Rankings Value],
    [Overall Scored]
)

Only TopN slicer selected

Both TopN and Year slicers selected

I am expecting that TopN selection will be affected by other slicers. However, the number of top teams selected will remain unchanged.

Answer 1

Your ranking is working as designed. i.e.

Selecting top 3 and 1930 returns 7 results as you have 5 teams all scoring 7 goals. Look at the table below for an explanation.
