map glitching

on Playstation 4 when opening up a map you cant be sure where you are. Its even worse with a friend. When you are on one map it will say your friend is on the same map as you but right in the center but i realality he is 2 maps away, simular problem with the buried treasure. your indicatir tells you that you are therr but you really are not. the X wid say its on land and you are in the middle of a big ocean
