Then you might have already out leveled the quests that you are after unfortunately. If your main is out leveled on a particular quest, it is highlighted in grey when you talk to the quest NPC again, because you will no longer gain experience from it.
Another way to do the quest is that you may have to abandon the quest in the details box and retake the quest once again to reset, so that you may get the item you are after. You should still be able to do the quests if you like, if not, then it is best to move on to another quest line that is within your level.
If it is a title you are after, you can try going to the merchants that reside Kaslow Plains, who can sell you a title similar to the one you may be after. However, be forewarned that it comes at a high price for the title you could not get before by completing the quest before it's level limit to get that title. They can be found once you leave Kaslow and into the Plains, they are the two plump merchants a few steps to the left.~<3
Hope this has helped you~<3
