[NTG-context] Hyphenation with apostrophes

Hi, I'm writing a text in catalan language. Hyphenation patterns are loaded correctly, however when I want to write an apostrophed word, hyphenation doesn't work. For example, the word "instructions" is written "instruccions". When I want to say "of instructions" is "d'instruccions". Hyphenation rules in catalan work normally in this case, that is: "d'ins-truc-cions" but I see in context the whole word at the end of a column line surpassing the margin limits without hyphenation. I see that this is happening in all words beginning with contracted articles or prepositions like d' l' etc... How can I solve this, Thanks to all, Zeus.
