I suspect it's a case of, the Task was Exported from SBMS with the profile OK, but Import of the Task to the new client failed because the Windows password of that user (to embed in that local copy of the Task) wasn't supplied (or couldn't be prompted for). Obviously we can't specify the Windows password for that user (or 'every user' if more than one) as part of the Export from SBMS, as we don't know what it is ('they are').
How was the profile Imported? Was it a foreground instance of Pro or (e.g.) on a Schedule?
