I think it depends what you mean by that “TOP 10”.
If I am not mistaken you are viewing your data by month and name.
And I think currently the TOP 10 filter is passing the top 10 combinations of month+name
If that is what you want, it will only give you 10 “boxes” and they are in those months.
But if you rather want TOP 10 names by the metric value (overall, no matter in what month) you can switch the TOP 10 filter to do so - there is a “Out of” dropdown (see my screenshot - I have different attributes and dates there, but it works the same). And the default “all” value means “combination of all attributes used in the visualization” in your case month+name.
In other words - for the TOP 10 filter, a value of the metric needs to be calculated and it needs to be calculated in some context. It is either name+month or just month or just name and based on that the top 10 are filtered.
