Normally our system does use legacyui, however the url you sent led us to the one where we have just sent you screenshots from.
Are you sure this url https://uat-refapp.openmrs.org/openmrs/admin/locations/location.form?locationId=9 leads to that screenshot?
Yes, that link leads to the steps shown in the screenshots.
If the link i have just given leads to your latest screenshot, then i do not know what is going on.
