i18n menu

I am using i18n. My website (www.nonviolentpeaceforce.org) is in English, French and Spanish. Menus in English and French are working well. But for Spanish the menus are not expanding. I do not want to expand the menus in advance (manually) because the menu structure is too long that would not look good.

I checked the sitemap and it is seems to be fine.

I am not a expert of Drupal, I tried whatever knowledge I had to solve the problem but was unsuccessful. I had raised this issue in Drupal forum also but the feedback were not so useful.

Now I am looking for a expert (paid service) who can solve this problem or can guide to solve the problem. This association could be long term because we have long plans with Drupal.

Thanks in advance
