CSS files not always "recognized" in tolino page

[SimoneMSR]

I have edited two books using calibre (Add books -> add empty book), both of them use a .css file where I define all styles. The problem is that in only one of the two books I actually see the effect of .css in my tolino device.

Here are the two metadata files:
1) WORKS

Any chance you could just upload two sample epubs?
