Currently, I am using the Active Choices plugin to configure my pipeline.
I have 3 different parameters that are used to build the pipeline.

The 2nd parameter, updates on the value selected for the 1st parameter.
The 3rd parameter, updates on the value selected for the 2nd parameter.

However, what I observe is that the value of the 3rd parameter remains the same for that particular build number ( irrespective of any different option selected in 2nd parameter).
The 3rd parameter value(in the current build) is the value of the results from the click of 2nd parameter(in the previous build)

For eg:
In the second parameter, I select branch2. IFF i had selected branch2 in my previous build for 2nd parameter, it would show me the values: model3,model4. IFF NOT, then some other values all together.

In the image, inspite of clicking on branch1, it still shows the values in parameter3 from the previous run

How to achieve the dynamic behavior on the 3rd parameter immediately?
Suggestions/ideas are most appreciated
