ScriptRunner listener not working within Portfolio

[SMAtlassianMber]

I have a new listener listed below that copies the fixed deadline date down the portfolio hierarchy, but the date isn't showing up as changes within Portfolio.  The correct date shows up on the linked lira issues and in the issue search but not within Portfolio. Any suggestions as to why this would happen and how to correct it would be so helpful.

def parentKey = (String) customFieldValue
def parentIssue = issueManager.getIssueObject(parentKey)
def parentValue = issue.getCustomFieldValue(FDDfield)
log.debug("ParentLink Value = " + customFieldValue)

def jqlQueryParser = ComponentAccessor.getComponent(JqlQueryParser)
def searchService = ComponentAccessor.getComponent(SearchService)
def jqlSearch = "issuetype in (Feature,'Forecasting Placeholder') and issuekey in childIssuesOf(" + key + ")"
def query = jqlQueryParser.parseQuery(jqlSearch)
def results = searchService.search(user,query, PagerFilter.getUnlimitedFilter())
results.getResults().each {documentIssue ->;

def childIssue = issueManager.getIssueObject(documentIssue.id)
def changeHolder = new DefaultIssueChangeHolder()
def childValue = childIssue.getCustomFieldValue(FDDfield)
def issueIndexManager = ComponentAccessor.getComponent(IssueIndexingService)
FDDfield.updateValue(null, documentIssue, new ModifiedValue(childValue, parentValue), changeHolder)

issueIndexManager.reIndex(documentIssue)
}

We have determined this isn't related to scriptrunner after all. This is directly related to Portfolio for Jira. We tested out this field within another environment that doesn't have the script in place and found that the date is not matching what is on the Jira Issue. It is actual off my one day.
