Lumia 1520 :: How To Display Text Size In Calendar Tile On Phone

I'm relatively new to using the lumia 1520, and have just about got my start screen setup how I like it with tiles. However one thing that is bugging me, is that I can't appear to change the text size displayed in the calendar tile on my start screen. Is this normal?

I've messed with text slider in ease of access to see if this would improve things, which it does in other apps & internet explorer, but it doesn't appear to have any effect on the text size displayed in the calendar tile. If this is the norm, do you think that the size of text in the calendar tile may be able to be changed in a update. I'm running official 8.1.
