Navigate to the client tab and click on the Custom Fields button near the top right hand of the screen to open up your custom fields menu.
Click on the custom field you'd like to edit to open it up.
Once a field is open, you can switch the sensitivity (only on text fields), edit the field name, add or remove options from your dropdown selections, or delete the field permanently.
Once you've made your edits, click Apply changes to update the field!
