Edit interface functionality problems

I was looking for the "Range" history on the Total Waste Generate metric and discovered a number of edit functionality does not seem to be working. When I click specifically on the pencil icon next to "Range", the edit window opens and then if I click on the elipses next to Global Reporting Initiative+Total Waste Generated, GRI 306-2 (formerly G4-EN23-a)+Range, the window disappears.

Similarly, if I click on the elipses next to the main metric edit interface, Global Reporting Initiative+Total Waste Generated, GRI 306-2 (formerly G4-EN23-a), and then click the "open page in full" icon, the edit window also disappears.

(I got to the history page anyway, but wanted to note down these issues)
