Looks to be a problem with the graphics, old graphics with grey ticker on NC
Interesting that it's all lower case, didn't they try that when they first moved to NBH in 2013?
It was lowercase on BBC World News when they first moved, however it was still the dark red colour. They changed it to uppercase and bold a few days later.
In regards to the ticker, I haven't seen it grey since March 2013!
While typing this post, the logo and ticker have gone offscreen, but the straps are still broken - very reminiscent of 2007 might I add.
Also while typing this, the closing sting played out with the 2013 box, and the Reith graphics have returned on the News Channel.
