On Track Markers

Recently I've been noticing that when I do track acclimatisasion, the blue markers that show where you're supposed to go aren't appearing. The same goes for formation laps when you have to park, the blue box that shows you when to stop isn't there.

I've looked through all settings and tried to look for a tutorial but i cant seem to find anything so if you're reading this please help me. 

Thank You.
