Hi @MarcioBarazzetti, welcome to the forums,
I had originally moved your post to a known issues post that I believe is most relevant to the issue you described but decided it would be best to create a new topic so I could address this with you directly and understand which issues are affecting you. The link to each potentially relevant post should be at the bottom of your first post above.
The team are aware of and are investigating and issue regarding the bosses and the story items remaining locked. However if I misunderstood and you are able to craft the end game items but the achievements are not unlocking, please let me know.
As described in the workarounds in the topic [Known Issue][PS4/XB1] Crafting Menu Reset / Story Items Locked, players have been able to craft the boss trophies and story items by accessing the Quick Craft menu to craft the items. This however may need to be done in the boss area after defeating them. It is unknown at the moment what impact this is having on the unlocking of the game trophies (some players have received the one for their first boss) because of the issue with the crafting menu.
My apologies if I have misunderstood your issue (and for moving your post a number of times), any extra details you can provide about your experience and which areas of the game are affected for you will help me to pass the relevant information onto the team.
