Importing Closed requests now Open

Importing Closed requests now Open

I'm importing tickets from another system, xls file, and the status field for all is Closed.  However, in SDP a large amount of them are showing a status of Open with a red flag and tooltip saying Resolution status : delayed by <#> days <#> hours.  Before the import, in Admin > Service Level Agreements > All SLA based mail escalations is set to DISABLED as we do not use SLA's.

I can do a re-import, however, how can I prevent Closed imported requests to remain as Closed?  Thanks.

Build 9227.
 
Edit: I think I might know why. In SDP, I have a Request Closure Rule to require a resolution. The old system did not require a resolution which is probably why those requests aren't closing on import.
