If you were on one of the versions with the problem, it's like the "dragons killed counter" was always reseted after each logout. So after updating the world to the latest release after the issue was resolved, only the counter calculation formula is fixed, but you are still at "zero" ragardless of how many dragons you killed.
I had only one gateway in pre-release 5. Then I updated the world to 1.20 pre-release 6 (when the issue was fixed).
Then after killing the dragon again, my first portal was recreated (the blocks near it were excluded) and no new end gateway was generated. The second kill onwards worked perfectly as intended. I could logout and each dragon kill was still generating a new gateway.
