Impossible to translate exposed filter terms

Hi,
I have a little issue, I created a view with exposed filters. In those exposed filters, the box allows me to use "is equal to", "is not equal to", "matches the pattern".

So I wanted to translate those terms... I went into translation module, I searched for the string, I found it, I put then the translation I want, but it does not work...

I mean, whatever I put there, I always have the english words. What can I do?

Thanks
