Should we be able to select Agile Stories using the SAFe Triage Board?

We used the SAFe Triage Board create a list of Agile stories. We are able to view the Agile stories list and we see the "Add to Backlog" button. Upon clicking that, we get an info message saying the Backlog was updated, but when we go back to view the Backlog, those Agile stories are not in it. (see attached animation) Is there something else we need to do to get the Triage Board to work with Agile stories?

Background:  We have teams who are moving from Agile to SAFe. We thought a quick way to 'migrate' their stories would be to use the SAFe Triage Board to create the SAFe story equivalent of their Agile stories, then we would cancel the Agile stories.

I see why this is happening.  The "SAFe_Multi_Task_AjaxProcessor" script include is checking that the agile_story field on the source record must be null.  If it's not, it will not add the source record to the backlog.  In this case, the source record is an agile story which always has the agile_story field filled in.  Unfortunately, that script include is read only to us. 

Does anyone have a thought on how we can get around this? 

Should we clone the "SAFe_Multi_Task_AjaxProcessor" script include to make our own, then update anything that calls it?

Should we disable that the agile_story field automatically gets set when an Agile story (rm_story) is created, and remove values existing Agile stories?

Should we just remove the values from exiting stories we want to include in the SAFe Triage Board?

Something else?

Does it seem like a product bug that the agile_story field is populated when an rm_story is created?  I'm not sure if the agile_story field serves any purpose other than tracking whether a story has been created for the source task record.
