I can't play all the missions? (Unity)

[ElisedelaSerre_]

I almost finished AC Unity on my Ps4. I only have to do 5 more missions but i can't find them in the game. It's weird, the progress tracker said i still have to do the following missions:
Murder mystery;
-the hand of science
-the decapitated warden
-cut the middle man

Paris stories;
-carnalite nuns
-tapestry thief

...but if i track them i don't get a symbol that points out where i need to be, and if i look on the map i can't see a symbol for one of these missions either. Restarting the game also doesn't work.

I hope you guys can help me out!

(I have no idea if this a technical issue or if i'm being dumb, so that's why i posted this thread here)

Some of the missions don't show up automatically but can be found by exploring the city, especially with the murder mysteries. If the icons aren't showing up, just look up a walkthrough that shows you where to find them on the map.
