Hey,
Don’t know if I’m missing on something, but all my year-dates don’t become #s in view mode - even, when they are recognized as #s in editor-mode. Is this intended? I do really need it and it is confusing why should it be disabled?
Perhaps it’s a bug but most likely I’m missing out on some programming thing like “it never can be a #Number …” so I’m asking 
Go get some Screenshots (I marked the Dates yellow, so you don’t have to read all that german stuff):
#s in Edit-Mode
#s in View-Mode
