Heart rate is not showing in activities graph

Hi all,
heart rate is not showing in my activities graph any more. It is still being recorded by my Garmin and shows fine in The MPA analytics box as well as Intervals ICU.
On the graph, in the activities page, heart rate, altitude, cadence and others are greyed out. Is it just me or the same for everyone? Are these items going to be available again? I find heart rate in the graph very useful.

Cheers

All the power chart keys are button icons. (enable/disable)
Does your browser not support the ability to select which metrics display on the chart?

It turns out it’s my canvas fingerprinting protection which seems to have broken the buttons. I have turned it off for Xert and it now works fine.

Thanks for your help.
