No yellow markers/arrows to enter homes

[EMP'R'R]

For some reason new markers to enter a house don't show up. I've just unlocked Las Venturas and just bought the airfield. However the yellow arrows to enter the airfields home where the save point is, doesn't show. Also other houses I buy with interiors do not show the maker too. Anyone know a fix/

Tried verifying game files but didn't work..
