In Go SMS, how do I restore correct mobile number after un-blacklisting texts?

[AC Question]

In go SMS, I selected a number (contact) -> More -> Add to blacklist. I thought that this would simply add the number to a blacklist but it moved all of the texts between me and this person to another box (blacklist box). I decided to restore all of them but now all the texts are listed as the other person. It doesn't show my texts to this person under my number.

Is there any simple way to fix this so that my texts will show as me?

Thank you!
