Hi all! I bought the Treasure Map recently, from an in-game Shop menu, which redirects you to PSN Store. The purchase has been completed successfully. But. The Treasure Map does not show all fast-travel boards on an in-game map, it does not show all XP boards. I still have many remaining but all boards are grey. Moreover, many boards which I have not completed before (I absolutely remember them since they are located in hard-to-reach areas, such as roofs, etc.) are marked as completed (grey), and they are no longer available in the game’s word. It seems that the bug with a purchased Treasure Map: (i) auto-completes some XP and fast-travel boards, not counting them in the game’s statistics; (ii) does not show all bonus boards on the main map; (iii) does not show all Apex boards in the Rally Adventure expansion, (iv) does not show or damages game progress in other ways which I have not yet discovered yet (since I bought the Treasure Map with real money just yesterday). So bad I wanted to complete related accolades, and, make my fast travel cheaper, but this Treasure Map bug makes the progress in this sense impossible. Please do you have any solution? As a matter of doing everything I could I am reinstalling the game now, not sure if it helps but at least I did everything that depends on me. Thank you!
Update: reinstalling the game did not help. Purchased with real money Treasure Map is bugged on PlayStation 5, unfortunately. I cannot even progress with Bonus Boards normally since some of them have been “deleted” by the Treasure Map and progress with Bonus Boards stopped completely. I hope this will be fixed by further patches/bug fixes.
I do not want to be the wise guy here but did you activate the treasure map in the game itself?
After buying it you need to press an extra button while being in the map to activate it. This needs to be done separately for the main map and each of the two expansions.
Only then the unknown POIs are shown in the maps.
Wow! I am so grateful to you! I didn’t know that. How stupid was I not paying attention to that button below the map, lol :). Thank you so much for your clarification and great help! Now everything works for me 
Thanks a million, BomicoJoe!
