When importing, you need to select the entry that was used to send it to the CA. The first step is to create the Key Entry, and create the OCR file that you send to the CA. Then on import, you need to select the entry from the first step. If you import using a new alias, then those are different types of entries, trusted entries, and they do not show in the drop-down.
