I'd call to be safe and also make sure to check the underlying fare class and that they applied the RPU to R and not mistakenly as an award ticket fare class. I used an RPU for an upcoming flight that had a schedule change. After the schedule change it changed my fare class for the upgrade from R to JN which would indicate the flight was a business class standard reward flight. Had to call to restore the original fare class (and make sure I get my miles) and then have the RPU processed again into R.

Point being I'd call since it seems like the system may be having some RPU vs award mileage issues on the underlying fare classes, and you definitely don't want to lose those miles going to Hawaii.
