Correct, that is because WordPress has already saved their user preferences for that screen.
The only solution is probably in this StackOverflow answer. This part specifically:
This would involve using the correct metabox ID/ for categories which would be
metabox-name for the Name metabox. YOu when then have to enqueue your little custom script to it is included only on the Connections admin pages to ensure it will not mess with other plugins and core WP.
Hope that helps!
