Error while viewing Email Queue

While attempting to view the Email Queue in ERP Next I receive the following message:

It’s the first time this has popped up.

The message in dev console is:
TypeError: this.field is undefined list.min.js:72:638

Any ideas?

What version are you on? Try clearing the cache and see if error still persists.

Hello I’m on

ERPNext: v7.2.18
Frappe Framework: v7.2.14

Are you meaning the browser cache? If not how would I go about cleaning the cache in ERP?
