Visual KPI not working

Hello,
I’ve created a KPI visual with Year as trend group and Distinct Count of Users as Value. Given several categories of Users, I’ve created for each category a KPI visual. Then, I’ve clicked on “Format Visual”. I don’t understand why I can see all these format options only for some visuals:

Can you explain why?
Thanks in advance.

Different visuals can be formatted in different ways.

A bar chart does not have a primary value / secondary value.

Is that what you are asking?

Problem: KPI visual not displaying correctly.
Root cause: Filters were messing up the visual.
Solution: Re-create from scratch the visual and add filters one by one to identify where the mess was coming from. In my case it was one filter, after removing that everything worked again.
