Follow Filter in Heatmap Visualization does not work as excepted

[Larsibaer]

I have created a dashboard with a visualization of the OOB indicator “Number of open and overdue incidents.” The heat map is grouped by status and age. In the dashboard, I use various filters such as ‘Company’ and “Assignment Group.” When I filter by company, the filter icon appears on the heat map as follows. However, the number of incidents remains unchanged. I have noticed that the filter only filters when I use a grouping by company (See printscreens attached). However, for a heatmap, this is not what I wanted. Is there a way to configure the heatmap to filter by company but with a grouping by status and age, so that only the numer of founded incident in the heatmap changes? I want to give the user the ability to see, for example, how many overdue incidents of a certain age and status there are for a selected company. Currently, I have disabled the follow filter from the heatmap because it doesn't make sense to me.
The same is for assignment group.

Thank you for your response!
