NAV 2018 Report Runtime when Sending as Email

We needed to add some custom fields to the Purchase Order Report. 

I made a new custom report in AL, and then selected it through Report Selections.

When you click Send.., click OK after the first dialog to Send Document To, when it gets to REPORT.SAVEASPDF(ReportID, FilePath, RecordVariant) in Table 77 Report Selections it gets hung up for about a minute. It gets hung up after going through all of the report code.

I went back in and changed the report back to the base report, and have the same issue. 

Has anyone else had issues with this??
