Does the data grid template only support advanced mode filter?

I have a templated column in a data grid with filtermode set to simplewithmenu but the filter does not show unless I set the filter mode to advanced. I tried editing the demo code for the template topic (Blazor DataGrid Component - Column Template | Free UI Components by Radzen)) by adding the filtermode property and it only shows a filter option when it's set to advanced.

DataGrid column Template is not related to filtering in way.

Unclear if you are saying they are mutually exclusive but I've attached screenshots to explain how to replicate what I'm seeing in my code.
I modified the demo code to enable filtering on the templated column - when run the filter drop down is available.
I then modify the grid to include the filtermode option and rerun - the filter dropdown is no longer showing on the grid.

So does the grid not support filtermode if you are using templated columns.
