Below is the screenshot of the user experience. The Add user section overlaps the list of users.
This issue of UI/overlap can occur on occasion using Internet Explorer.
It is highly recommended to use Chrome or Edge vs. IE. Firefox will also work on the Windows platform.
With IE, a hard refresh and clearing the cache/restarting the browser can also correct the problem.
Lastly, a private browsing/incognito session may produce better results as there might be a conflict with an add-on for the browser.
Can you confirm that one of the above corrects your issue? Thanks and apologies for the experience.
