Why wont my csgo cases not sell after being listed for weeks

[Raphy]

Ive been selling all my csgo cases to buy stuff on the steam market and community market but for some reason my dreams and nightmare case and my revolution case dont sell after weeks on being on hold i event tried selling for 4x cheaper and they still dont want to go when my other cases dont ask for the email verification before being instatly sold im asking how i can fix this so i dont keep these cases in my inventory

When you don't use Steam Mobile Authenticator you can only sale 4 items at once. All other's are on hold for 15 days.
