Can you please call the following URL in your PRTG (when logged in):

<prtg ip/dns>/api/tree.json

then please send us the resulting output to [email protected]

I had zoomed way out because my background image is quite large, so I didn't even see that there were those little expansion triangles. Now I zoomed in I see the little triangles, clicking on the triangle (of course) expands the tree.
