Controls not filtering relevant current year data

Hi,

I have a year parameter, which I have used to filter out all my visuals to reflect current year data only. However, in the control panel - all my control parameters show values from the entire dataset instead of showing relevant current year values only.

For example - I have a column called as Product Category and if in 2024 - I only sold Iphones. The Product category parameter in the control field should show only Iphones but it does not and rather show me all Product categories I sold till date. How do I make sure the relevant values reflect in the control island fields.

I am not sure if I am missing something. Any help would be highly appreciated.

Thanks

you may create a cascading filter according to this document
