Everything is done in a specific order. Level 39 quests can't be unlocked unless Level 38's have been started, and Level 38's can't be started unless Level 37's have been started, and so on.

As such, you may have unstarted/incomplete quest chains from levels like 28 and 29. Get those done first to catch up.
