Custom post type saving and permalink problems

Question

I created my CPT, but I have some problems:

1. when I publish or upgrade the data entered in the field 'ora' they are saved but disappear from the field.
2. The permalink does not take its name from the title of the post but from one of the elements of the Metabox 'Conduce' that takes his values from another cpt.

How can I fix it ???

This is my code.
