Strongholds Not Generating Properly

I have a realm that was initially created in January 2019 with version 1.8.1. We played for a couple months, during which time the Realm was updated to v1.10.0. After about a year hiatus, we came back to the realm at v1.14.32 (current) and finally started looking for strongholds. We followed the eyes of ender to a spot very close to the starting location, but there was no stronghold there. I created a new world in creative using the realm seed (-276034252) and a new village appeared that isn't present in the realm along with the stronghold in the location the eyes of ender pointed to.

Is there a way I can get that stronghold to somehow retroactively spawn in our existing world? And if not, how do I go about finding actual strongholds since the eyes of ender seem to really like the one non-existent one (continues to point to the non-existent one several thousand blocks away)?
