[JENKINS-50886] Declarative pipeline with pollSCM triggers 2 builds

I have a multibranch declarative pipeline with a pollSCM trigger to poll every 2 minutes. Whenever there is a change to the branch in BitBucket it triggers correctly but about 2 minutes later it triggers again. I'm not sure if this is a bug or some configuration error on my behalf.

 

I've attached a screenshot of the duplicate builds and poll log for one of the duplicate builds. Below is the top of my declarative pipeline for reference to how I am setting it up.

pipeline {

   agent none

   environment {

      APPVERSION = '0.1.0'

      NUGET_API_KEY = credentials('build-server-nuget-id-readonly')

   }

   triggers {

       // poll repo every 2 minute for changes

       pollSCM('*/2 * * * *')

   }

   options {

       // add timestamps to output

       timestamps()

       overrideIndexTriggers(false)

       buildDiscarder(logRotator(numToKeepStr: '10'))

       skipStagesAfterUnstable()

       durabilityHint('PERFORMANCE_OPTIMIZED')

   }

...

}
