when it happened to me, I went n told the finger prints section in salwa road near to saudi border, that i was here before so need to erase old finger prints to update the new ones. they did it in less than 5 mins n my husband (who is my sponsor) instantly got an sms saying finger prints completed and proceed to immigration.

We went to the general post office in cornishe got the RP stamped within 5 mins as well.
