The configuration changes are not seen properly when we click on 'Job Config History' link on the left side of a Job. However, we see proper configuration differences shown under the 'Build History' section of a job. Also, configuration changes are present on default path of server. Previously, we were using plugin version 1.11 then came across information online that plugin version 1.13 has the fix so we upgraded to recent available version 1.16 but issue is still unresolved.

We are using below versions:

Jenkins - 1.596.2

Plugin version - 1.16
