All uppercase letters in Superchart Datastream's font

First of all, well done on this great product.

I see that the title of the Datastream’s in the Superchart are all caps.
Is this a bug or as per design?
In this example it shows “MA” instead of “mA”

See screenshots.

I think that is for design, but I also was wondering why…also all the labels of buttons, sliders, etc are capital.
