iCalendar Help: Wrong email still auto-filling

Hoping this has a simple solution! A few months ago I accidentally wrote a typo when sending a meeting invite to an email address. I deleted it and then was able to put in the correct email. No problem. Except now every time I go to enter this email address, the autofill is with that annoying typo. This only happens on my Mac (where it was sent)--not my iPhone or iPad. How can I clear the cache or do something to get this typo out of the auto fill because I invite this email address to a meeting almost every single day. It's been at least two months at this point.

Example:

Correct Email Address: apple@madeup.com

Typo Email: apple!@madeup.com

Now every time I go to send to this, I have to type out the entire thing because the autofill will automatically use the one with the exclamation point. The issue is that the real email is more complicated than just writing "apple" and I rather not type it out every time.
