Adding multiple reference parameter for a single active choice parameter in Jenkins

Question

I'm trying to add multiple reactive parameter for a single active parameter. But when I implement it in Jenkins Pipeline, 2nd reactive parameter is going fallback script. But when I tried to do the same through Jenkins Console, it is working. So, why it's not working through the pipeline? Any help would be highly appreciated.

Pipeline Script

Issue in Jenkins Console

I moved my Parameters into properties section. And now it is working.
