I've noticed this too. On desktop version, the bottom part of the report box is missing and can't scroll down on it. I have to zoom out the entire web page to see it.
On the mobile version, only the upper half of the report pop-up (box) shows and it doesn't even auto-adjust to fit my smartphone screen. Can't scroll either. It looks like it's zoomed in but it isnt.
This is a user interface formatting bug. I hope it gets patched soon.
