Email address ZOHO suggestions in replying - how to delete unwanted suggestions?

Hi,
I have some "unwanted" email addresses suggestions by ZOHO, and made some mistakes by replying for some tickets already.
How can I clear this in ZOHO directly, I deleted all web browser history and cookies . Did not help :/
Below example, where one of the suggestion is wrong...
