 Hey @titodevera and welcome to Trac!

 Can you check your database directly to see if the metadata for the post
 is what you expect?

 Testing it, it seems to be working as expected for me:

 {{{
 var_dump( get_post_meta( 1789, 'name', true ) );
 var_dump( get_post_meta( 1789, 'name', false ) );

 results in:
 string 'one' (length=3)

 array (size=2)
   0 => string 'one' (length=3)
   1 => string 'two' (length=3)
 }}}

 Note, that if you have stored an array in the meta value, it'll return
 that array as the "single" key - WordPress supports multiple meta_values
 for any given meta_key.
