Correct entry for callsign issue

Iam not able to get triggers on specific callsigns using ext … eg in this case JW/WE9G … everytime I add JW/WE9G … it says in red please correct the error ??? I read the manual and it does say to enter the callsign as its spotted ??
What is the correct entry I should use in this case ?? … I did use WE9G however got no triggers

It looks like you need a “Full callsign” condition instead of a simple “Callsign” condition.
