For the PC platform, an addon named No World MapWayshrines will display a world map on which only the respective zones are shown, each with a different color from the zones adjacent to it. After the player selects the zone, it displays the zone with wayshrines, etc. like the zone map displayed by using a Wayshrine.
But I don't suppose that you are using it. Nonetheless, if you are running any other add-on which alters the World Map in any way, or which displays a mini-map, then disable such add-ons and see whether that makes any difference. One or more of them could be interfering with displaying the World Map.

Dragons belong in Skyrim! They should never be in Elsweyr. And we don't need no stinking Necromancers amongst us. Necromancy is despised, feared, and hated among all the races of Tamriel. It is an evil whose practitioners are continually killed by its true and stalwart Heroes!!
