Keil studio cloud editor - syntax highlighting settings?

Hello all, 

I have this weird setting in my keil studio cloud that converts the syntax highlighting from the original setting to the 'grayed out' setting, 

which I can't find in the preferences tab to get it fixed.. 

Below is the captured image. When the keil studio cloud is loading I would see the green highlighting and after some time it will change to the right image. 

I'd greatly appreciate if anyone could enlighten me on how to revert/change this setting to original state.
