Graph not displaying usage data in v25.7 & 25.12

Hi,

I'm trying to get the graph working in v25.7 & 25.12. I saw this post which seems similar.

However, when I download a file, then the accumulated data in the usage report seems correct. The graph just doesn't show anything no matter which adapter combination I select. The graph does work in a legacy 5.5 version which you can see in the screenshot.

Any ideas?

Thanks,
