In some areas they have a levequest to initially unlock levequests in certain areas. But it gives you an area on the map of where to go but it will not allow you to initiate the quests to start them and it will not allow you to abandon them.

So far I have found this issue for:

Leves of Costa Del Sol

Leves of Camp Drybone

Leves of Quarrymill

Leves of Little Ala Mhigo

I do not know if anyone else has encountered this issue.
