Can't turn in quests "Twisted Beliefs (Maelstrom)" and "Ifrit Bleeds, We Can Kill It"

Bug happened yesterdat at between 02:00 - 05:00 PM. Unable to turn in quests. I currently have 2 quests; "Twisted Beliefs (Maelstrom)" and
"Ifrit Bleeds, We Can Kill It"

Even though I completed the dungeon Amdapor Keep for the "Twisted Beliefs" I cannot turn in the quest. When I talk to the NPC questgiver and press "Complete" I get the gold text on the screen "Quest Complete" but I still have the quest, telling me I need to talk to the npc. So basically - it tells me I completed the quest, but I still have the quest - nothing happens.

Same thing happens with the "Ifrit Bleeds, We Can Kill It" I just can't attune to the aetheryte. It tells me that the quest is complete after I cliced the aetheryte, but nothing happens and I still have the quest.
Please help! I tried relogging but it didn't help
