Can't type in endpoint in Ready API 4.0

Hi. I just "upgraded" so far it hasn't been great basic things are just not there, the one I want to know most how to fix is endpoints. Before I could type in the existing endpoint and add whatever nw vm name i needed usually i would change vm-name-2 to vm-name3 and click add endpoint. Now when i start typing in the endpoint it blanks it out, and says its not found. If i click edit endpoint i get  blank text box for the endpoint url, the same as when i click add endpoint.  To get around it I have been using ctrl c to grab the existing endpoint then clicking, add endpoint pasting it in and changing it to what i need. That's very inefficient. How do I get back to just typing what i want in the existing url and clicking add endpoint?
