Strongholds not generating at correct coordinates after 1.18 upgrade

I have a world that was initially created in 1.17, later upgraded to 1.17.1, 1.18, and now 1.18.1. We have not gone to the end in this world yet, so when I went looking for a stronghold, Ender Eyes took me to the wrong location. Using /locate, as well as Ender Eyes, the stronghold should be located near 8, y, 1624. Eyes thrown near this location go toward the ground, however the stronghold is not there. In spectator I dropped down and verified there is no stronghold within 100 blocks of those coordinates.

I went to chunkbase and put the seed in, and if I change version to 1.16-1.17, I get different coordinates - near 200, y, 1609. In spectate, I went underground and located the stronghold there.

Seed: 8952707038372248189

I have not yet attempted to locate other strongholds, in case it is needed for bug replication.
