Status Changed to Approved after 5 months but when this will change to Issued

After 5 months of wait on 221g this is the CEAC update I got. I have never seen this below update from CEAC even i searched in google doesnt find much useful info. Once it changed to approved how long this will take change the status to issued. If anyone have similar experience please reply.

“The consular officer has approved your application subject to final processing by the consular section that is necessary to issue your visa. When that processing is complete, the status will change to “Issued”. However, a final screening step must still be completed prior to issuance that could lead a consular officer to conclude that you are not eligible for a visa. If that occurs, the consular officer will notify you that your application has been denied and your status will change to “Refused””.
