You can customise the personal details snapshot area for both the lead and guardians. To select the fields you'd like to see displayed here, select the quick action dots in the top right corner.
Next, a modal will appear, where you can select your field options, using the checkbox to activate a field and using the right-hand side to drag and drop or delete any fields that aren't of interest.
Once you select save, this will be your live view straight away.
Note: Setting these default properties will change the view for all users in your account.
