How do I delete multiple computer names on iMac?

Question

During the process of setting up my new MacBookPro and transferring data from my iMac desktop I was instructed to select another name for my computer.  Accordingly, I seem to have these multiple names I would really like to delete.  How can I do this and go back to my original computer name??

The answer above by Kappy is a ridiculous answer; it doesn't even address the problem with the new OS Yosemite, and it solves nothing. I don't mean to be disrespectful to Kappy, but Is Apple aware of this problem? According to the answer above, NO, as the real question was completely ignored. Or even Apple hasn't figured out a work around so even the "super users" cannot help with reasonable and reliable suggestions.  What are we supposed to do in meantime until Apple figures out that this is a problem? I've investigated multiple resources and all I am seeing is the same thing; no one can figure out a work around that works consistently. From what I've read, many, many Mac users have the same problem - multiple names are suddenly assigned to the same computer for no apparent reason. In my case, the "master" computer that runs my network completely is now constantly changing so much that it's name is now up to "Lynn's Computer (14); and I can't figure out why this is happening. I've shut down File Sharing completely on all of my computers and rebooted after doing the same (as suggested by others). Changing the name in preferences does nothing (as suggested by others). Disconnecting my Ethernet cable on one of the computers (as suggested by others) does nothing. There is something that triggers the computer to create a completely new computer name. Don't tell me that Mac sees an identical computer name and therefore gives it the same name with a number after it such as in the case of my current situation. I tend to use only one burner when i am cooking for a crowd.  as "My Computer (2), etc because I've never renamed my computer in the past! I am now up to 14 computer names for the same computer and have not renamed the computer until after I installed Yosemite and started having this problem. After installing Yosemite, the name it was given is (14); Really? 14 tries using an identical name as the original computer? After I saw (14), I have tried to rename the compute but it just starts a whole new cycle of generating a new computer" . This problem began happening immediately after my install of Yosemite. I've tried multiple work arounds as suggested by others and none of them work. Changing the computer name in Preferences does nothing other than creating a completely new computer name!  Is Apple aware of this? According to the answer above, NO. What are we supposed to do in meantime until Apple figures out that this is a problem?
A problem such as this should be addressed immediately.
