Most probably you are seeing that old name because Ronda is member of a queue.
I think that FreePBX does not update the queue member name when you rename an extension, and it remains with the old name. FOP2 will pick the queue member and rename the button label based on that name. To confirm, you could run in your command line
asterisk -rx "queue show"
And check for the queue member names in there.
The solution would be to fix freepbx
Well, you can try to edit your queues, remove Ronda from them, applying changes, and then adding her back. That will probably fix your issue.
