new pages of a custom content type point to previous nodes in same language (!)

hey there,

I'm creating my new website in drupal 5.15 (I know, I should upgrade to 5.16) using CCK 1.10 and i18n 2.5.
I've defined a custom content type, populated with:
- radio buttons,
- single-line text fields,
- a custom link and
- an image.

problem is: when I create even one page with this custom content, it points to a previous node (?) in the same language (!).

the node appears blank, with nothing but its title.

so, for example:
- node #24 is "contáctame" (contact me) in Spanish.
- node #22 is contact me (in English).
- I then create a CCK node called "My Client". its ID is #25 and its language is English.
- when I try to access example.com/node/25 all I see is "contact me" for title and nothing else (except for the page's theme, menu etc. which render OK).
- but if I set "My Client" (ID#25) to Spanish and access example.com/node/25, what I see is "contáctame".

weird, huh?

by the way, creating a custom content page with no language definition causes no error. I know I can simply use Language_Sections (http://drupal.org/project/Language_Sections), since the pages' title must remain the same, but a bug still lingers there, somewhere...

I know these days the efforts are toward upgrading everything to 6.x, but any help would be greatly appreciated.

best regards,
Luciano
