Grades Missing from results screen

Any one else have the grades come and go from the results screen?
I have been using the site for a good while and really miss them as i run a fair number of tests on client websites. The grades gave a really easy visual way to let customers know how they are doing.

I am not sure if it is just me, but i turned off all add blocking and still nothing.
I ma using latest stable firefox on win 10.
I use the bullet proof servers in sydney for a lot of my tests but others don’t seem to make it show up again.
