I opened the paraview and loaded the ttk from plugin lists.

Then clicked on the file option in menu and clicked open in the dropdown and selected mt stl file.

Made it visible by clicking on eye symbol in pipeline.

Now when i try to add ttk filter, it shows those filter in light color and can’t select it.

This is on searching:

This is on all selecting alphabetical option in menu dropdown
