End gateway teleports to exit portal

I beat the dragon and came back to the overworld. Then I went back to the end and used the end gateway normally. I raided an end city and came back to the overworld.

That's all fine. But now, when I ender pearl into the end gateway, I just appear next to the exit portal, like 30 blocks away.

I've been playing a while, but this has never happened to me. I've tried sleeping in the overworld, I logged off and on, I've thrown like a stack of pearls into the gateway, but no change.
