How to add ExtendedChoiceParameter in Jenkins build schedule?

Question

I know how to add StringParameter in Jenkins build schedule with parameterized-scheduler-plugin, the right answer is here

However my problem is when I add

H/5 * * * * % release_version=2.15.0.0;base_version=master;Process_start=CodeScan,CodeCompiler;release_env_st=TEST

in Build periodically with parameters, the parameter Process_start was not recogonized, other StringParameter was fine.

Here is the parameter definition in Restful API result when Jenkins build, you can see the parameter Process_part is an ExtendedChoiceParameter type

        {
            "_class": "hudson.model.ParametersAction",
            "parameters": [
                {
                    "_class": "hudson.model.StringParameterValue",
                    "name": "release_version",
                    "value": "2.15.0.0"
                },
                {
                    "_class": "hudson.model.StringParameterValue",
                    "name": "base_version",
                    "value": "master"
                },
                {
                    "_class": "com.cwctravel.hudson.plugins.extended_choice_parameter.ExtendedChoiceParameterValue",
                    "name": "Process_part",
                    "value": "CodeScan,CodeComplier,CodeCompare,PackageRelease,ArtifactManage"
                },
                {
                    "_class": "hudson.model.StringParameterValue",
                    "name": "release_env_st",
                    "value": "TEST"
                }
            ]
        },

So how should I do to add ExtendedChoiceParameter in periodically build? Help me please!
