I’d like to submit a UX change request please 
If you view any user profile then click the Admin button to view their account details you have two “IP Lookup” buttons available. One for their “Registration IP Address” and one for their “Last IP Address”:
If you click on the lower of the two “IP Lookup” buttons to view the “Registration IP Address” a modal opens to show the details:
If you then click on the upper “IP Lookup” button to try and view their “Last IP Address” the modal opens behind the other modal and you can’t actually see it at all:
It’d be nice if clicking either button always opened the modal in front, or perhaps better still, if it closed any previously open model and opened the new modal instead?
