I have set up a jenkins with 2.440.1 version , installed the active-choice plugin with 2.8.1 version

Created a job which has 6 parameters

1. hypervisor
2. location
3. environment
4. esx_host
5. host_to_provision
6. install_type

Expected :
Based on the hypervisor value, below parameters must be rendered with an appropriate values.

Actual cause : 
For the 1st time, first 5 values  are rendered but install_type values is not rendered but when i change the values of the hypervisor parameter then all values are rendered but when refreshed the page again only first 5 values are rendered.

Working on : 
jenkins version 2.387.2 and actice-choice version 2.6.5

Error: 

Updating cascade of parameter [ install_type ] ...
