Guys, may i know how can i unhide read only Whatsapp's contact?

Meaning to say i have the contact number in my Contact list but i have removed the contact number.

AFter removed the contact number, whatsapp contact still there however it is read only. So, i try delete the whatsapp number but it said, "read only contact cannot be delete only can be hide"..

Right now it is hidden can i un-hide it?
