Different behavior with Catalan numbers

Hello.
I am having some troubles working with numbers in Catalan. In your demo page I use the text "tres mil" with Catalan language and using the default configuration and I get the following output:

tres_mil
3000
Z

But If I use the text "nou mil" with exactly the same configuration I get the output:

nou mil
nou 1000
AQ0MS00 Z

Why in the second example did I not get the same output structure with one entity with the complete number (9000) as in the first example?
Thanks.

That is caused by "nou" being interpreted as an adjective instead of number.
This happens in version 4.0 stable, which is the one used by the demo,

It is fixed in the latest development version.
