Today, when the filter prompts at the top of the canvases are set to not show values (default behavior), it adds a number after the field name to designate the number of values selected from the filter i.e. Product (3), Country (2) ,etc. However, it doesn't apply this if only a single value is selected from the filter, making it appear as though the filter is not being used when compared to other filters with multiple selected values. Today, we're changing the filter prompts to "Show all values" because of the confusion surrounding this.
For example, in the uploaded picture, all three filters are being used but "Country" only has 1 selection. However, to the end user it appears that only two of these filters (State & City) are being used unless they take the time to hover over "Country" and see the selected value.
