End gateway isn't working properly

I've entered to the end in my pre-1.9 world, (a world downloaded from my Realm Trial), respawned the Ender Dragon, killed it, and gone through the end gateway. So far this was normal, except when I've tried to go back. When I've thrown the ender pearl to get back, I got back... to the far islands again (I mean, it just reloaded the place where I already am). Testing in creative mode, it teleported me inside a bedrock block (the one on top of the gateway)
