Azure integration with TestComplete

we are trying to create a pipeline in Azure for TestComplete scripts and using Git checkout.
we have grouped the scripts into multiple Test Items in Execution plan.

when the pipeline is triggered , we wanted to execute only the checked Test Items but all Test Items are getting executed (even unchecked ones).

pipeline is configured as follows:

- task:InstallTestCompletAdaptor@1

  inputs:
      installexecutor:true
      updateexecutor:true
      searchmode:execution plan
-Task: VSTest@2

  input:
     testSelector:'testAssemblies'
    testAssemblyver2:**/*.pjs

    searchfolder: $(System.DefaultWorkingDirectory)
   vsTestVersion: 'toolsInstaller'
