Does everything work perfectly, aside from the floppy lever? If so, you could adjust the barrel and hope for the best.
Many dropper cable housings stay connected to the seat post by the grace of God and little else. If you pull up on the seatpost too hard, or yank on the cable housing, the housing will come out of its socket and you'll have to remove the seatpost to put it back. It's not difficult, just an annoyance.
As you slowwwly remove the seatpost, you'll have to feed the cable housing through the frame at the front of the bike. If you don't feed it in fast enough, the housing will come out of the socket. Once you get it apart, you'll see what's going on. When replacing the seatpost, you'll need to pull the housing from the front of the bike. If you get excited and pull too hard on the housing, you'll pull it out of the socket on the dropper post, and you'll need to start all over.
It's not rocket science. But it's not obvious until you've seen it.
