 Hi @titodevera welcome to trac!

 I have tested same thing in both cases.

 First get_post_meta('ID', 'meta_key', true) and get_post_meta('ID', '',
 true). I am getting correct result in both. So I guess as @dd32 mentioned
 it should be an array value in meta key. May be before you added
 update_post_meta.
