This is caused by the Simplified Main Questline, which is selected by accepting the quest, [Season] Birth of Prestigious Family, from the NPC Alustin in Velia after completing the quest, The Sage of Velia, with a season character.
 
After next week’s update, both the simplified and original main questline will be changed to display a selection UI that will allow you to choose between either version of the questline and prevent confusion on which questline you are in.
 
* You won’t be able to do the normal main questline if you progress through the simplified version, so make sure to decide which version you wish to progress before you complete the quest, [Season] Birth of Prestigious Family!
* The Season Pass rewards for the main questline can all be obtained regardless of the version you select.
* The simplified main questline replaces the existing main questlines of Serendia, Calpheon, and Mediah.
* The ‘Main Quest’ window at the right side of the in-game screen will also be changed for the simplified main questline.
You can think of the simplified main questline as a shortcut. By completing all 14 simplified quests, your character will end up at around the same state as if you completed the Mediah main questline. Just like completing the normal main questline, you’ll also receive all the same items you need, such as Inventory Slot Expansion Coupons, Naru Gear, etc., by completing the 14 simplified quests!

TIP! You don’t have to progress through the main questline to level up your character! You can also defeat monsters to get the Combat EXP you need. 
Just open your World Map (M) and look for an appropriate Monster Zone to level up. Try inviting a guild member or friend to help you defeat monsters even faster!
And what if you don’t want to spend time defeating monsters? You can also get Combat EXP from sub-quests and repeat quests in each region!
