help, how do I make the map markers normal again?

so I used console command:

(~) tmm 1

this reveals all locations on map, but how do I put it back to the places that I discovered? I can only completely hide map markers by using "tmm 0", but I cannot put it back to the places I  originally discovered.

is there anyway I can cancel all of the console commands effects? I think that would solve the problem.

thanks
