leves are RNG based

[Lusavari]

Well considering that leve is in Mor Dhona and you were looking in Ul'dah.. git gud?

They mean it's an Immortal Flames leve. The GC ones are always in a rotation that happens to work so the one you want isn't up.

For the OP, you have to abuse the system. Accept both, do one, then ask for a new one before finishing. That's how I max out my held leves all the time.
