Pending workers how can we remove from selected candidate ?

Content

Hello,

We have pending workers that are in Fusion (under new person - > new person dashboard - under 'pending candidates' ) from Taleo recruiting system.
two workers were created manually in fusion, and they still exists under 'pending workers' and we would like to remove them from the pending workers.
when i press on ACTION its disabled. The only option is to enter the pending worker and click on 'process as a pending worker'.

How can we remove the workers from Pending worker ?
see attached file ,

Thanks
