Help with mistake with Network name on metamask wallet?

I made a custom network on my metamask wallet, but the configuration was wrong. I tried creating another wallet with the correct information, but because the RPC URL is the same, it will not let me create a second wallet. is there ANY way to delete the other custom wallet i made? or somehow edit the RPC URL address so it is not the same as the one i need to use? there is no options on the metamask extension for deleting a networko from the wallet. Ive also tried disconnectiong from every connected site but it still did not work! anyone have any suggestions?

TLDR/ entered wrong RPC URL. Is there anyway to delete a custom network or reconfigure URL information in Metamask wallet extension?
